F(x) = 7x - 13
y = 7x - 13
7x - 13 = y
7x = y + 13
x = (y + 13)/7
f^-1(x) = (x + 13)/7

Answer:

BC=11

Step-by-step explanation:

we need to find BC

and we  know that

AB= x+2

AC=13

BC=2x+11

A, B and C are collinear

that means that

AB+BC=AC

x+2+2x+11=13

3x+13=13

3x=0

x=0

so BC=2(0)+11

BC=11
