Answer:
x = 91, y = 89, z = 31 Fourth choice
Step-by-step explanation:
x = 180 - 51 - 38 = 91
y = 180 - 91 = 89

Answer:
<u>f(f¹(14)) = 134</u>
Step-by-step explanation:
Given :
Find the value of f(14) :
- f(14) = 3(14) + 2
- f(14) = 42 + 2
- f(14) = 44
Therefore, f(f¹(14)) = f(44).
Solving :
- f(44) = 3(44) + 2
- f(44) = 132 + 2
- <u>f(f¹(14)) = 134</u>
I believe the answer is -10
