Answer:

y= 1/2x-1

Step-by-step explanation:

The equation of a line is y= mx+c

m represents the slope of the line

c represents the y-intercept

So we plug in our information into the equation.

The slope is 1/2 so y= 1/2x + c

The line crosses at (0,-1) which makes -1 the y-intercept as the line crosses at this point on the y-axis.

Therefore, y= 1/2x-1

A brand new truck was purchased for $45.000. A year later the truck was worth $40,480, and the year after that $35.622. If the r

Marat540 [252]

Answer $32,045

Step-by-step explanation: Ok, to get the rate of depreciation all we we have to do is $45 divided by $40.480 you would get 1.1116.

The rate of depreciation: 1.1116

If you do $45,000 divided by 1.1116 you'll get 40,322.

It won't be the exact same answer because you would have to divide for an hour.

Now we can skip to the important part: $35,622 divided by 1.1116 = $32,045

Therefore the truck will be worth $32,045 in 10 years!

I hope this helped
