Answer: f(x) and g(x) are inverses of each other
<u>Step-by-step explanation:</u>
To find the inverse of a function, swap the x's and y's and then solve for "y"
f(x) = 5x + 2
y = 5x + 2
Swap:
x = 5y + 2
<u> -2 </u> <u> - 2 </u>
x - 2 = 5y
<u>÷5 </u> <u>÷5 </u>

Answer:
d=9
Step-by-step explanation:
Answer:
34.60°
Step-by-step explanation:
Answer:
47.1 inches
Step-by-step explanation:
As your hint says C=π*d
C= circumference which is what you are solving for
they said to use 3.14 for pi
d= diameter which is 15 inches
C= 3.14*15 = 47.1
