Answer:
Given: f(x)=\dfrac{1}{9}(x-2)
We need to find the inverse of f(x).
Step 1: Set f(x) = y
y=\dfrac{1}{9}(x-2)
Step 2: Switch x and y
x=\dfrac{1}{9}(y-2)
Step 3: Solve for y, Isolate y
x=\dfrac{1}{9}(y-2)
Multiply by 9 both sides
9x=y-2
Add 2 both sides
9x+2=y
y=f^{-1}(x)
Hence, f^{-1}(x)=9x+2

Answer:
39 athletes
Step-by-step explanation:
There is a total of 45 people on the bus. This INCLUDES the athletes (A), 2 coaches and 4 managers.
Therefore, we need to sum A, 2 and 4 and equal it to 45:
2 + 4 + A = 45 so we need to used equation d.
To calculate how many athletes are on the bus, find the value of A:
2 + 4 + A = 45
Subtract 2 from both sides: 4 + A = 43
Subtract 4 from both sides: A = 39
