A study was conducted to determine the relationship between the age, x, in years of a
certain brand of motorcycle and its value, y, in dollars. The equation y = -750x +8,500
best models the data. Based on the equation, what is the estimated value of a motorcyde
that is 5 years old?
А
$3,750
B
с
$7,750
D
$12,250

Respuesta :

The estimated value of a motorcycle that is 5 years old is $4750.

What is a linear equation?

A linear equation is in the form:

y = mx + b

Where y,x are variables, m is the rate of change and b is the initial value of y.

Let y represent the value of the motorcycle after x years.

The value is given by:

y = -750x + 8500

After 5 years (x = 5):

y = -750(5) + 8500 = 4750

The estimated value of a motorcycle that is 5 years old is $4750.
