Answer:
y = -3x + 13
Step-by-step explanation:
y = -3x + 13 is the only formula there that has a slope -3 (as shown in -3x) and is the only one that passes through point 5,-2.
The equation of the line that passes through the point (5, -2) and has a slope of -3 will be y = - 3x + 13. Then the correct option is C.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The slope of the line is given as,
y = -3x + c
The equation of the line is passing through the point (5, -2). Then we have
- 2 = - 3(5) + c
- 2 = - 15 + c
c = 13
The equation of the line that passes through the point (5, -2) and has a slope of -3 will be y = - 3x + 13. Then the correct option is C.

Answer:

Step-by-step explanation:
Consider the equation 5x^2-10x+c=0. What values of c result in the equation having a complex solutions? Represent your answer on the number line
Answer:
When we have a quadratic equation:
a*x^2 + b*x + c = 0
There is something called the determinant, and this is:
D = b^2 - 4*a*c
If D < 0, then the we will have complex solutions.
In our case, we have
5*x^2 - 10*x + c = 0
Then the determinant is:
D = (-10)^2 - 4*5*c = 100 - 4*5*c
And we want this to be smaller than zero, then let's find the value of c such that the determinant is exactly zero:
D = 0 = 100 - 4*5*c
4*5*c = 100
20*c = 100
c = 100/20 = 5
As c is multiplicating the negative term in the equation, if c increases, then we will have that D < 0.
This means that c must be larger than 5 if we want to have complex solutions,
c > 5.

The perimeter of a square is 8x +2 units. What is the length of one side? Explain your answer .
Answer: 2x + 0.5 unit
Step-by-step explanation:
A square has 4 equal sides. Therefore, its perimeter is calculated by adding the four sides.
Since the perimeter of a square is 8x +2 units, to get the length of one side, we divide the perimeter by 4. This will be:
= (8x + 2)/4
= 2x + 0.5
Therefore, the length of one side is 2x + 0.5 unit

Andrea has a balance of $135.68 in her savings account. Every Friday Andrea goes to the bank to deposit $170.50 and withdraw (take out) $60. If she does this every Friday for 4 weeks, how much money does Andrea have in the bank? Show all work or explain how you got your answer.
Answer
577.68
Step-by-step explanation:
first you subtract 60 from 170.50 to get 110.5. After that you multiply by 4 to get 442. take 442 and add it to 135.68 to get 577.68. so it would look like this
170.500-60=110.5 110.5 x 4=442 442+135.68=577.68

what is the line perpendicular to =4-6 and passing through the point (8,12)
Answer:
y= -1/4x + 14
Step-by-step explanation:
- the slope of a perpendicular line is the negative reciprocal of the original line, so the slope of the new line is -1/4
- now, y= -1/4 x + c, to find c we substitute the values of x and y from the given point [ (8,12) ]
- (12) = -1/4*(8) + c, after you rearrange you get c = 14
- place the value of c to get y= -1/4x + 14
Kerry is looking foward to a skiing trip this weekend she checked the tempature yesterday and today, and overnigjt is dropped from 12 F to -5 F what is the total difference in the tempature
Answer:
-[tex]17^\circ F[/tex]
OR
[tex]17^\circ F[/tex] decrease in the temperature.
Step-by-step explanation:
Given that:
Temperature at the night = [tex]12^\circ F[/tex]
Temperature in the morning = -[tex]5^\circ F[/tex]
To find:
The total difference in the temperature = ?
Solution:
Difference of any quantity is given by the Final value of quantity minus Initial value of quantity.
Therefore, the difference is given as : -[tex]5^\circ F[/tex] - [tex]12^\circ F[/tex] = -[tex]17^\circ F[/tex]
Negative value in the difference indicates that there is a decrease of the quantity.
So, the answer is:
-[tex]17^\circ F[/tex]
OR
there is decrease of [tex]17^\circ F[/tex] in the temperature.

Can someone please how to do fractions in the lowest terms
Answer:
In order to out a fraction in lowest terms, you must divide by the Greatest Common Factor, or GCM, of the numerator and denominator in the fraction. Let's say we have the fraction 25/100. We know that the greastest common factor of 25 and 100 is 25, as 25 ÷ 25 = 1 and 100 ÷ 25 = 4 so 25/100 in lowest terms is 1/4:
25 25 1
___ ÷ ___ = ___
100 25 4
If the GCM of a fraction equals 1, the fraction is simplified. Because the only common factor of 1 and 4 is 1, we know this fraction is simplified.
1 1 1
__ ÷ ___ = ___
4 1 4

Answer:
x = 81, y = 68, z = 99
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Consider the triangle on the left, then
x = 180 - (36 + 63) = 180 - 99 = 81
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
x is an exterior angle of the triangle on the right, thus
13 + y = x , that is
13 + y = 81 ( subtract 13 from both sides )
y = 68
Consider the triangle on the right
z = 180 - (13 + y) = 180 - (13 + 68) = 180 - 81 = 99

Answer:
2n-4
Step-by-step explanation:
The value of n for the given condition is 2(n - 2).
What is simplification?To simplify means to make anything easier. In mathematics, simplifying an equation, fraction, or problem means taking it and making it simpler. Calculations and problem-solving techniques simplify the issue. By eliminating all common factors from the numerator and denominator and putting the fraction in its simplest/lowest form, we can simplify fractions.
Given equation
(n + 8) + (n − 12) =
n + 8 + n - 12
solving constant separately and variables separately,
2n - 4
the common factor of 2 and 4 is 2
2(n - 2)
Hence the simplified form of an equation is 2(n - 2).

Find the measure of each numbered angle
The measure of each numbered angles are ∠1 = 56°, ∠2 = 56° and ∠3 = 74°.
What is Angle?An angle for any figure is formed by two rays which joins at a common point called vertex or node.
Usually angles are measured in degrees or radians.
Consider triangle PMQ
The sum of the interior angles of a triangle is 180°.
∠MPQ + ∠QMP + ∠PQM = 180°
58° + 66° + ∠1 = 180°
∠1 = 180° - (58° + 66°)
∠1 = 180° - 124°
∠1 = 56°
Now, ∠1 and ∠2 are vertically opposite angles. Hence they are equal.
∠2 = 56°.
Again, for triangle NQO
∠2 + ∠3 + 50° = 180°
56° + ∠3 + 50° = 180°
∠3 = 180° - (50° + 56°)
∠3 = 180° - 106°
∠3 = 74°
Hence ∠1, ∠2 and ∠3 are 56°, 56° and 74° respectively.

An equilateral triangle with side lengths of 7 units is translated 3 units to the right. What is the length of one side of the triangle after the translation, in units? 3 units
Answer:
[tex]Sides= 7\ units[/tex]
Step-by-step explanation:
Given
[tex]Sides= 7\ units[/tex]
[tex]Translation = 3\ units[/tex] (to the right)
Required
Determine the length of one side after translation
It should be noted that when a shape, line, object is being translated by shifting its position, only the position of the shape, line or object changes not its length
This implies that, the length of the sides of the equilateral triangle remain unchanged.
Hence:
[tex]Sides= 7\ units[/tex]
