The general equation for depreciation is given by y = A(1 - ), where y = current value,
A = original cost, r = rate of depreciation, and t = time, in years.
The original value of a car is $24,000. It depreciates 15% annually. What is its value in 4 years?

$12,528.15

Step-by-step explanation:

Using the given equation y = A(1 – r)^t you can calculate the car current value :

y = 24000 * (1 - 0.15)⁴ = 24000 * 0.85⁴

y = $12,528.15

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
