8. The Johnsons framed a family picture to hang on the wall. The perimeter of the frame is 72 inches. Use the formula P = 2ℓ + 2w to find the length of the frame if the width is 19 inches.

A. 15 in.

B. 17 in.

C. 20 in.

D. 19 in.

B. 17 in.

Step-by-step explanation:

2l + 2w = 72

2l + 2(19) = 72

2l + 38 = 72

2l = 34

l = 17

Hope this helps!

step-by-step explanation:

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
