Answer:
X = 100$ + 5a$
Where X is the price of a car rent
And a is the amount of mile travel
I don't have an idea of what the answer is to be honest.
Y=1/x solve for x
x=1/y now reverse lables...
y=1/x
Yes that is the same equation you started with. What that means is the the inverse function in this case produces the same exact graph :)
