Question

Bryn is riding his bicycle at a constant speed from school to the library. His distance from the library in kilometers x hours after leaving school can be modeled by the equation Y=20-12X. What is the distance between the school and the library in kilometers?

Answer 1

The distance is 20km

Explanation:

Given

`y = 20 - 12x`

Required

The distance between
`the\ library\ and\ the` school

The function represents the distance
`y = 20 - 12x`

So, when x = 0.

This implies that he has not started moving.

So:

`y = 20 - 12 * 0`

`y = 20 - 0`

`y = 20`
