Answer:
D
Step-by-step explanation:
An isoceles triangle has two eqial sides and angles wich give it exactly one axe of symmetry
A. 2(length + width) >= 134
length + width >= 134/2
length >= 67 - 29
length >= 38 ft
Replace f(x) with y
Y = 2x -5
Swap roles of x
X= 2y-5
5+x =2y
Divide by 2
5+x /2 = y
Replace y with inverse f^-1(x)
Answer= f^-1(x) = 5+x / 2
