Line:
3x+y=7
y=-3x+7

Slope of Perpendicular Line: 1/3x

For the perpendicular line to contain point (6,-1) the y-intercept would be (0,1), thus the equation of the line would be y=1/3x+1

y=1/3x+1

The annual rate of depreciation, x, on a car that was purchased for $9,000 and is worth $4,500 after 5 years can be found using
Zolol [24]

Answer:


Step-by-step explanation:

We know that exponential formula of depreciation

A=P(1-x)^t

where

P is the initial amount

x is the interest rate

A is the amount after t years

we are given

The annual rate of depreciation, x, on a car that was purchased for $9,000

so, P=9000

we can plug value it

A=9000(1-x)^t

we are given

when x=5 , A=4500

so, we can plug it and solve for x

4500=9000(1-x)^5

\frac{9000\left(1-x\right)^5}{9000}=\frac{4500}{9000}

\left(1-x\right)^5=\frac{1}{2}

x=-\left(\frac{1}{2}\right)^{\frac{1}{5}}+1

x=0.12945

so, interest rate is 13%

now, we can plug x

and we get

A=9000(1-0.13)^t

A=9000(87)^t
