Answer:
f(g(x)) = x
Explanation:
In order to prove that one function is the inverse of the other, all you have to do is substitute in the main function with the inverse one and solve. If the result is x, then it is verified that one function is the inverse of the other.
Now for the given functions we have:
<span>f(x) =5x-25
</span><span>g(x) = (1/5)x+5
We want to prove that g(x) is the inverse of f(x).
Substitute in the above formula and compute the result as follows:
f(g(x)) = 5(</span>(1/5)x+5) - 25
= x + 25 - 25
= x
The final result is "x", therefore, it is verified that g(x) is the inverse of f(x)
Hope this helps :)

Answer:
if it's less than 7.66km use Royal, if more than 7.66 use Queen's
Step-by-step explanation:
To get the answer you can set up mutliple equations
For Queen's Cab Company
2.70 + 0.20x = ?
for Royal Cab Company
1.55 + 0.35x = ?
Since you didn't give a distance which is what will determine which is cheaper we can solve as a set of equations.
2.70 + 0.20x = 1.55 + 0.35x
1.15 = .15x
x = 7.66
So this lets you know that at 7.66 km Royal cab company becomes more expensive due to their pence per km.
So if it's less than 7.66km use Royal, if more use Queen's
