A. 6 and b. 12. You take 3.6 and divide it by .6 then multiply by 2 for the second answer

A

Formula

Total time = Time for 1 commercial * Number of commercials.

Givens

Total Time = 3.6 minutes

Time for 1 commercial = 0.6 minutes

# commercials = x

Solve

3.6 = 0.6 * x    Divide both sides by 0.6

3.6 / 0.6 = x

x = 6 commercials.

B

Just use the formula again, only this time, use 0.3 for the amount of time needed for 1 commercial.

3.6 minutes = 0.3 * number of commercials

3.6/0.3 = number of commercials.

12 = number of commercials.

Given the graph below, which of the following points would be included in the graph of the inverse of the function?
Svetlanka [38]

Answer : (1,-1)

a line through the points (-1, 1), (0, 2), (1, 3)

To find the point in the graph of inverse function we interchange x  and y values

For point (-1 , 1) , the point on inverse function is (1, -1)

For point (0 , 2) , the point on inverse function is (2, 0)

For point (1 , 3) , the point on inverse function is (3, 1)

so (1,-1) will be  included in the graph of the inverse of the function

X=-12-6y <br>-4x+5y=-39<br>slove by the system of substitution
Artist 52 [7]
X = -6y - 12
4x + 5y =-39

                  4x + 5y = -39
     -4(-6y - 12) + 5y = -39
-4(-6y) + 4(12) + 5y = -39
       24y + 48 + 5y = -39
               29y + 48 = -39
                       29y = -87
                            y = -3

x = -6y - 12
x = -6(-3) - 12
x = 28 - 12
x = 6

(x, y) = (6, -3)
