Question

If Y is the midpoint of TW, TY = 4x - 4 and YW = 2x + 8, find TY.

A. 5
B. 6
C. 14
D. 20

Answer 1

i think the problem is asking about the intersection point of the graphs of these functions

Answer 2

Since Y is a midpoint, TY=YW. Therefore, 4x-4=2x+8. Solving this linear equation we get:
2x=12
x=6.
Since TY=4x-4, TY=4*6-4=20
