Which system of equations does this graph represent?
sveta [45]
Equation of the linear graph is given by: (y - (-7))/(x - (-3)) = (-2 - (-7))/(2 - (-3)) (y + 7)/(x + 3) = (-2 + 7)/(2 + 3) = 5/5 = 1
y + 7 = x + 3
y = x - 4

Also, for the parabola: -(3)^2 + 2 = -9 + 2 = -7
Therefore solution is:
y = -x^2 + 2
y = x - 4

A new car is purchased for $50,000 and over time it’s value depreciates by one half every 5 years. What is the value of the car
Setler79 [48]

The value of the car after 5 years would be $23914.85

<u>Explanation:</u>

Given:

Worth of the new car = $50,000

Every 5 years the value depreciates by 1/2

i.e., every 5 years the value depreciates by 50%

So, we can say that every year the value depreciates by 10%

The worth of the car after 7 years would be

W = C (1 - \frac{D}{100} )^t

where,

W is the depreciated value

C is the current value

D is the depreciation rate

t is the time

Substituting the value in the equation we get:

W = 50000( 1 - \frac{10}{100} )^7\\\\W = 50000 (\frac{9}{10} )^7\\\\W = 23914.85

Therefore, the value of the car after 5 years would be $23914.85
