Option C is correct. To get system B, the second equation in system A was replaced by the sum of that equation and the first equation multiplied by -3. The solution to system B will be the same as the solution to system A.
What is equations ?
An equation is a mathematical statement that shows the equality of two expressions. It usually contains one or more variables and is solved to find the value of the variable(s) that make the equation true. Equations are used extensively in mathematics, physics, engineering, and many other fields to describe relationships between quantities and to solve problems.
The given system of equations is:
System A:
x + y = 5
3x - 2y = -35
And the solution to this system is (-7, 2).
To obtain System B, we need to manipulate the equations in System A. Let's start by isolating y in the first equation:
y = 5 - x
Now we can substitute this expression for y into the second equation and simplify:
3x - 2(5 - x) = -35
3x - 10 + 2x = -35
5x = -25
x = -5
Now that we have x = -5, we can substitute it back into either of the original equations to solve for y:
x + y = 5
-5 + y = 5
y = 10
So the solution to System B is (-5, 10).
Comparing the two solutions, we see that they are not the same. Therefore, the correct answer is A. To get System B, the second equation in System A was replaced by the sum of that equation and the first equation multiplied by 3. The solution to System B will not be the same as the solution to System A.
Therefore, Option C is correct. To get system B, the second equation in system A was replaced by the sum of that equation and the first equation multiplied by -3. The solution to system B will be the same as the solution to system A.

Using the bag of marbles below, find the probability of pulling a blue marble two times in a row. After pulling the first blue marble, you do NOT replace it in the bag before pulling the second one. Each marble has an equally likely chance of being pulled. Answer as a simplified fraction.
The probability of picking two blue marbles is 1/21.
What is the probability?Probability is used to determine how likely it is that a random event would occur. The probability of a random event happening lies between 0 and 1. If it is certain the event would happen, the probability value is 1 and if it is certain that the event would not happen, the probability value is 0.
Probability of picking two blue marbles = (number of blue marbles / total number of marbles) x (number of blue marbles -1 / total number of marbles - 1)
Total number of marbles = 7

As a result, the Moon orbits the Earth roughly 2.8 billion times while the Sun revolves once around the Milky Way's nucleus.
How is earths rotation calculated?
One cycle of the Sun around the Milky Way's nucleus is thought to take between 225 and 250 million years to complete. The synodic month, or the length of time it takes the Moon to complete one orbit of the Earth, lasts roughly 29.5 days.
We must divide the total time of one orbit of the Sun around the Milky Way by the amount of time it takes for the Moon to orbit the Earth once in order to determine how many times the Moon orbits the Earth during one orbit of the Sun around the Milky Way's centre.
The result is (Total time for one orbit of the Sun around the centre of the Milky Way)/(Time for one orbit of the Moon around the Earth) = (225 million years x 365.25 days per year)/(29.5 days per orbit of the Moon) = around 2.8 billion orbits of the Moon around the Earth.

A dilation has center (0,0). Find the image of the point L(-4,3) for the scale
factor 3.
Answer: To find the image of point L(-4,3) after a dilation with a scale factor of 3 and center at the origin, we need to multiply the coordinates of point L by the scale factor.
The formula for dilation is:
(x', y') = (kx, ky)
where (x, y) are the original coordinates, (x', y') are the coordinates of the image, and k is the scale factor.
In this case, k = 3 and the coordinates of point L are (-4, 3).
So,
x' = kx = 3(-4) = -12
y' = ky = 3(3) = 9
Therefore, the image of point L(-4, 3) after the dilation with a scale factor of 3 and center at the origin is (-12, 9).

If you place 37 foot ladder against the top of a 15 foot building
I you place the 37 foot ladder against the top of the 15 foot building, it will reach a height of 52 feet.
If you place a 37 foot ladder against the top of a 15 foot building, then the ladder will reach a height of 52 feet (37+15=52). To calculate this, you can use the formula for addition, which is x + y = z, where x is the height of the building, y is the height of the ladder, and z is the total height the ladder will reach. In this case, x = 15 and y = 37, so the total height the ladder will reach will be z = 15 + 37 = 52. This means that if you place the 37 foot ladder against the top of the 15 foot building, it will reach a height of 52 feet.

You rent an apartment that costs $1200 per month during the first year, but the rent is set to go up 11% per year. What would be the rent of the apartment during the 8th year of living in the apartment? Round to the nearest tenth (if necessary).
The rent of the apartment during the 8th year would be approximately $2491.4.
To calculate the rent of the apartment during the 8th year, we need to apply the 11% increase per year for a total of 7 years (from the 2nd to the 8th year). Here's the calculation:
Rent for the 2nd year:
$1200 + (11% of $1200) = $1200 + ($132) = $1332
Rent for the 3rd year:
$1332 + (11% of $1332) = $1332 + ($146.52) = $1478.52
Rent for the 4th year:
$1478.52 + (11% of $1478.52) = $1478.52 + ($162.64) = $1641.16
Rent for the 5th year:
$1641.16 + (11% of $1641.16) = $1641.16 + ($180.53) = $1821.69
Rent for the 6th year:
$1821.69 + (11% of $1821.69) = $1821.69 + ($200.39) = $2022.08
Rent for the 7th year:
$2022.08 + (11% of $2022.08) = $2022.08 + ($222.43) = $2244.51
Rent for the 8th year:
$2244.51 + (11% of $2244.51) = $2244.51 + ($246.90) = $2491.41
Therefore, the rent of the apartment during the 8th year would be approximately $2491.4.

y =
The relationship between the number of times Trevor turns the crank, x, and the height the box has been lifted, y, is a linear equation y = (3/5)x.
What is a linear equation?
A linear equation is an algebraic equation in which each term is either a constant or a product of a constant and a variable raised to the first power (i.e., the variable is not squared or cubed). The general form of a linear equation with one variable, x, is:
ax + b = 0
Now,
We are given that there is a proportional relationship between the number of times Trevor turns the crank, x, and the height the box has been lifted, y. Let k = constant of proportionality.
Then, we can write the equation as:
y = kx
We also know that Trevor turns the crank 5 times to lift a box 3 feet.
Now
3 = k(5)
Solving for k, we get:
k = 3/5
Substituting this value of k in the equation, we get:
y = (3/5)x
Therefore, the equation for the relationship between the number of times Trevor turns the crank, x, and the height the box has been lifted, y, is y = (3/5)x.

To find the explicit formula for the nth term of the sequence 23, 19, 15, we need to look for a pattern in the sequence. We can observe that each term in the sequence is obtained by subtracting 4 from the previous term. Therefore, we can write the recursive formula for this sequence as:
a₁ = 23
aₙ = aₙ-1 - 4, for n ≥ 2
To find the explicit formula, we need to use the recursive formula to eliminate the dependence on the previous term. We can do this by repeatedly substituting the recursive formula into itself, until we get an expression for an in terms of a1:
a₂ = a1 - 4 = 23 - 4 = 19
a₃ = a₂ - 4 = (a₁ - 4) - 4 = a1 - 8 = 23 - 8 = 15
a₄ = a₃ - 4 = (a₁ - 8) - 4 = a1 - 12 = 23 - 12 = 11
From this pattern, we can see that each term can be written as:
aₙ = a₁ - 4(n-1)
Substituting a1 = 23, we get the explicit formula:
aₙ = 23 - 4(n-1)

Lorie Reilly decides to go back to college. For transportation, she borrows money from her parents to buy a small car for $7,200. She plans to repay the loan in 7 months. What amount can she deposit today at 5.25% to have enough money to pay off the loan?
Lorie should deposit $6,986.05 today at 5.25% to have enough money to pay off the loan in 7 months.
What amount can Lorie Reilly deposit today at 5.25% to have enough money to pay off the loan?To determine the amount that Lorie should deposit today to have enough money to pay off the loan.
We use the simple interest formula for accrued amount.
A = P( 1 + rt )
Where A is total amount, P is initial amount, r is interest rate and t is elapsed time.
Given that;
Accrued amount A = $7,200Time = 7 monthsrate R = 5.25%Principal P = ?First, converting R percent to r a decimal
r = R/100
r = 5.25/100
r = 0.0525
Next, we put time into years for simplicity,
t = 7 months / 12 months
t = 7/12 year
Plug the values into the above formula.
A = P( 1 + rt )
P = A / ( 1 + rt )
P = $7,200 / ( 1 + ( 0.0525 × 7/12 ) )
P = $7,200 / ( 1 + 0.030625 )
P = $7,200 / 1.030625
P = $6,986.05
Therefore, the principal or initial amount is $6,986.05.

The amount she should deposit today to have enough money to pay off the loan would be = $1,060
How to calculate the amount that should be deposited today?The cost of the small car that Lorie Reilly needs to buy for college = $7,200.(P)
The number of months that she plans to repay the money = 7 months = 0.58 yr.(T)
The rate at which the money needs to be deposited = 5.25%. (R)
The simple interest = Principal× Time × Rate /100
Simple interest = 7200× 0.58 × 5.25/100
= 21924/100
= $219.24
The amount she is expected to pay after 7 months = 7200+219.24 = 7419.24
The amount she should deposit today to have enough money to pay off the loan = 7419.24/7 = $1,060( approximately)

At dominos, each pizza is cut into 8 slices. Chris ate 5 slices from a pizza with a diameter of 20inch pizza, what is the area of the slices Chris ate?
Answer: The area of each slice of pizza can be calculated by finding the area of the whole pizza and dividing it by the number of slices.
The radius of the pizza is half of the diameter, so the radius is 20/2 = 10 inches.
The area of the whole pizza can be calculated using the formula for the area of a circle:
Area = π × radius^2
Area = π × 10^2
Area = 100π square inches
Since there are 8 slices, each slice has an area of:
100π square inches / 8 = 12.5π square inches
Therefore, the area of the 5 slices that Chris ate is:
5 × 12.5π square inches = 62.5π square inches
This is approximately equal to 196.35 square inches, when rounded to two decimal places.

Jaya spots an airplane on radar that is currently approaching in a straight line, and that will fly directly overhead. The plane maintains a constant altitude of 7300 feet. Jaya initially measures an angle of elevation of 16^∘ to the plane at point A. At some later time, she measures an angle of elevation of 28^∘ to the plane at point B. Find the distance the plane traveled from point A to point B. Round your answer to the nearest tenth of a foot if necessary
The distance the plane traveled from point A with measures an angle of elevation of 16°, to point B with measures an angle of elevation of 28°, is equals to the 11,728.6feet.
Jaya spots an airplane on radar that is currently approaching in a straight line start from point O in above figure, and that will fly directly overhead.
Altitude that plane maintain,h = 7300 feet
Initially, measure an angle of elevation to the plane at point A = 16°
Measure an angle of elevation to the plane at point B = 28°
Now, Let the distance between point A and point B be equal to 'x feet' and distance between point B and point C ( base) be equal to 'y feet'. So, distance between point A to point C = (x + y ) feet. We have to calculate the distance the plane traveled from point A to point B, i.e., x feet. See the above figure carefully, we see in right angled triangle BOC, tan 28° = 7300/y --(1)
In right angled triangle AOC,
tan 16° = 7300/(x + y) --(2)
Cross multiplication in equation (2)
=> tan 16° ( x + y ) = 7300
=> x + y = 7300/tan 16° --(3)
from equation (1), y = 7300/tan 28°
=> y = 7300/0.5317 = 13,729.55
so, x = 7300/tan 16° - y = 7300/0.287 - 13,729.55
= 25,458.12 - 13,729.55
= 11,728.58 ~ 11,728.6
Hence, required distance is 11,728.6feet.

Step-by-step explanation:
False, it is 3 units to the left
For any function,
[tex]f(x)[/tex]
the function transformation of
[tex]f(x - h)[/tex]
implies a transformation h units to the left
If h is the positive, this implies a transformation to the right
If h is negative, this implies a transformation to the left.
Here's since
