Answer:

(-6,-5)

Step-by-step explanation:

X+y=-11

solve for x

x=-11-y

substiute x value into 2nd equation

2x-3y=3

2(-11-y)-3y=3

-22-2y-3y=3

-5y=25

y=-5

substitute -5 for y in either equation to find x

x+y=-11

x+-5=-11

x=-6

Answer:

C and E

sorry for the late answer

Answer:

Step-by-step explanation:

Both sides of the equation are exactly same.

It means regardless the value of x the equation is true.

The equation has infinitely many solutions.

As both sides are equal

There present infinite number of solutions

rotated 180 degrees clockwise around the origin: (x , y) -> (-x , -y)

Answer:The question is a little incorrect, the ice sheet thickness should be 2m and not 222m.

The required function formula is,

S(t) = 2 - 0.25 t

Step-by-step explanation:

Here, the initial thickness of the ice sheet = 2 meters,

After 3 weeks, the thickness of ice sheet = 1.25 meters

Total changes in the thickness in 3 weeks = 2 - 1.25 = 0.75 meters,

⇒ Total changes in the thickness in 1 weeks = 0.75/3 = 0.25 meters,

Since, the ice is melting with the constant rate.

⇒ The rate of ice decreasing = 0.25 meters per week.

⇒ Total changes in t weeks = 0.25 t meters

The new thickness of ice after t weeks = Initial thickness - Total changes in t weeks.

⇒ S(t) = 2 - 0.25 t

Which is the required function's formula.

Answer:

the constant is 3 the coefficant is y and the varible is a and the factors of 9 are 18 and 27

Step-by-step explanation:

Answer:

The constant is 3

The coefficient is 12

The variables are both A and Y.

Disclaimer: I'm not sure about this next one, but I believe it's right.

9x factors are 3x, 1, and 9x.

If you wanted me to factor it, then it'd be something like 3x(3)

Step-by-step explanation:

A constant is a number that is by itself. Variables can't be constants. In this case, the only number that is by itself, that isn't a variable is 3. Therefore, 3 is the constant.

A coefficient is a number that accompanies the variable. Normally in a math equation, a variable is multiplied by a number. In this case, A is being multiplied by 12, so 12 is the coefficient.

The variable is the letter that represents any number. In this case, there are two variables, A and Y. They both represent numbers that can differ. So, A and Y are the variables.

The factors of 9x are 3x, 3, 1x, 1, 9x, and 9.

9 times 1x is 9x, 9x times 1 is also 9x.

3 times 3x is 9x, and 3x times 3 is again, 9x.

Answer:

area = 2184 ft²

Step-by-step explanation:

height² = 60² - 36² = 3600 - 1296 = 2304

height = √2304 = 48

base = 36 + x

x² = 73² - 48² = 5329 - 2304 = 3025

x = √3025 = 55

base = 36 + 55 = 91

area = 1/2(h)(b) = 1/2(48)(91) = 2184 ft²

Answer:

B

14

I think it is right :D

Step-by-step explanation:

Answer: B, 14

Step-by-step explanation:

The median is the number in the middle of the set if the numbers are in order.

And if there is an odd amount of numbers.

The number in the middle of the list is 14.

If the list doesn't have an odd amount of number you add the 2 middle ones and take the average so divide by 2.

Answer:

Assuming π is represented by 3.14, the correct answer is [tex]50.24m^2[/tex].

Step-by-step explanation:

Because the question is asking for the area of the shaded region, you can ignore the non-shaded versions of the diagram. The formula of finding the area of a circle is [tex]\pi r^2[/tex], where r is the radius of the circle. Since the radius of the shaded circle is [tex]4m[/tex], you can infer that the area of the shaded region would be [tex]4^2 * 3.14[/tex] = [tex]16*3.14[/tex] = [tex]50.24m^2[/tex].

Answer:

It's A

Step-by-step explanation:

Got it right on the practice :)

Based on the data presented , the answer is that Yes, it show repeated and periodic behavior. and thus the data indicate that a sine regression is appropriate in this case.

This occurs as our Moon is said to orbits around Earth. the side of the moon that is facing the Sun is said to be illuminated due to the sun's brightness, just like when the Earth's daylight side is also said to be illuminated by the Sun.

We tend to have a “new Moon” only when our Moon is said to orbit  around the Earth and thus moves it between Earth and the Sun.

See options below

Using the information above, plot the data points. Does this data indicate that a sine regression may be appropriate in this case?

a. Yes, it shows repeated and periodic behavior.

b. Yes, it shows a curve increasing from left to right.

c. No, the points are random.

d. No, the points depict a parabola.

Answer:

  ∠CBE = 59°

Step-by-step explanation:

Adjacent angles of a parallelogram are supplementary.

  ∠BCD +∠CDE = 180°

  ∠BCD +∠CDB +∠BDE = 180°

  (21x -5) +34 +(4x+1) = 180

  25x +30 = 180

  25x = 150

  x = 6

∠CBE = ∠CDE = 34 +(4x +1) = 4x +35 = 4(6) +35

∠CBE = 59°

Answer:

X = 3.01

Step-by-step explanation:

To solve for x, you first need to get x by itself. So you would minus 19.95 from both sides. Which would then be

5x = 15.05

Again x is not by itself so you would divide both sides by 5, the eqation would then be

x = 3.01

Which is the answer. If you want you can double check your work by putting the answer back in the eqaution.

5(3.01) + 19.95 = 35

If the statement is true that means you have the right answer

15.05 + 19.95 = 35

35 = 35

We are correct! Hope this helps with your question and how to do others like it.

Step-by-step explanation:

The value of x is 10.

In general, the term "proportion" refers to a part, share, or amount that is compared to a total.

According to the concept of proportion, two ratios are in proportion when they are equal.

From the triangle it can be assume that ΔPSR is similar to ΔPQR.

Then, the ratio of corresponding sides of triangles are proportion.

So, PQ/ PS = QR/ RS

9/15 = 6 /x

9x = 90

x= 90/9

x= 10

Thus, the value of x is 10.
