Question

a used car already has 40,000 miles on its odometer. the average owner will drive 12,000 miles per year. which function best models the linear relationship? y = 12,000x 40,000 y = 40,000x 12,000 y = 52,000x 12,000 y = 12,000x - 40,000

Answer 1

12,000x + 40,000
I took the same test and this was the right answer :)

Answer 2

The function best models the linear relationship is y = 12000x + 40000 .

Explanation:

As given

A used car already has 40,000 miles on its odometer.

Let us assume that y represented the total miles travelled by the car.

As given

The average owner will drive 12,000 miles per year.

Let us assume that number of years be x.

Distance travelled in x years = 12000x

Thus

Total distance travelled by the car = Distance travelled in x years + Distance travelled already shown in odometer .

y = 12000x + 40000

Therefore the function best models the linear relationship is y = 12000x + 40000 .
