After three years, the value of a new car decreased from $25,000 to $14,000. What was the percent decrease in the value of the car?

Step-by-step explanation:

In this problem we are required to find the percentage decrease in the value of a car that originally cost $25,000

if the present value is now $14,000

we can solve for the percentage decrease by presentment the original cost of the car by the original cost and multiplying by 100

i.e = (14,000/25,000)*100

= (14/25)*100

= 0.56*100

= 56%

Hence the value of the car has decreased by 56%

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
