How much will it be worth in 4 years?
Give your answer to the nearest penny where appropriate.

The car will be worth £28,870.12 in 4 years

Step-by-step explanation:

The equation for the value of the car after t years has the following format:

In which V(0) is the current value, and r is the annual constant depreciation rate.

Colin buys a car for £31300. It depreciates at a rate of 2% per year.

This means that

So

How much will it be worth in 4 years?

This is V(4).

The car will be worth £28,870.12 in 4 years

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
