Answer:

-2

Step-by-step explanation:

slope equation: (y2-y1)/(x2-x1)

lets use (-4, 9) as x1 and y1 and (3, -5) as x2 and y2

when plugged into the equation we get (9+5)/(-4-3) which ultimately equals -2.

The value in dollars, v(x), of a certain truck after x years is represented by the equation v(x) = 32,500(0.92)x. To the nearest

max2010maxim [7]

Answer:

The value of the truck is worth $27,508 after two years.

Step-by-step explanation:

We are given the following in the question:

$v(x) = 32,500(0.92)^x$

where v(x) is the value of truck in dollars after x years.

We have to estimate the value of truck after 2 years.

We put x = 2 in the equation.

$v(2) = 32500(0.92)^2\\v(2) = 27508$

Thus, the value of the truck is worth $27,508 after two years.
