A
22.5
D
m = [?]

m = 4

Step-by-step explanation:

ABCD ~ QRST, therefore, their corresponding side lengths brae proportional. This implies that:

10/m = 22.5/9

Cross multiply

m*22.5 = 9*10

22.5m = 90

Divide both sides by 22.5

m = 90/22.5

m = 4

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
