Suppose you start with a full tank of gas (15 gallons) in your truck. After driving 5 hours, you now
have 3 gallons left.
If x is the number of hours you have been driving, then y is the number of gallons left in the tank.
At what rate is your truck using gas? State your answer as a reduced fraction.

the answer is 0.3175 hope that you ^w^

also you might actually want to put this picture up if you want people to solve it luckily i remember this question

if you need , reply with more info. u.

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.

one set of data has more variation than the other. hope this !
