In the image below, DE∥BC. Find the measure of EC. Set up a proportion and solve for the measure. Show your work and label your answer

1 ft

Step-by-step explanation:

From the diagram;

Therefore

Also, AB=8+2=10ft, AD=8ft, AE=4ft. We substitute to get:

Simplify to get:

But AC=AE+EC

This implies that,

5=4+EC

EC=5-1

EC= 1 ft

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
