Question

In its prime, Mr. Ford’s 2002 Focus would get 36

Answer 1

Answer:

The fuel economy is 36 miles per gallon. For each mile 1/36 gallon will be used.

Initial volume is 13,2 gallons and x is the number of miles.

Our equation is:

• y = 13.2 - 1/36x

or

• y = -1/36x + 13.2

Answer 2

STANDARD FORM:

y = mx + b, where m is slope and b is y-intercept.

__________________________________________

ANSWER:

For one mile, it takes 1/36 gallons and first it has 13.2 gallons in it.

Let the no of miles be x.

So, equation becomes

• y = - 1/36x + 13.2
