Answer: x= -7

Step-by-step explanation:

subtract 8x from both sides of the equation which would leave you with 2x+18=4

then you would subtract 18 from each side of the equation leaving you with 2x= -14

the divide by 2 on both sides of the equation giving you the answer of

x= -7

your brand new 20,000 car will depreciate to 2,000 at a constant rate in ten years. Write a linear model relating the value "v"
koban [17]
Define
v =  value after t years.

Therefore the linear model is
v = mt + c
where
 m = depreciation rate
t = years since purchase
c =  constant

When t=0, v = 20,000, therefore
20000 = m(0) + c
c = 20000

When t=10, v = 2000, therefore
2000 = 10m + 20000
-18000 = 10m
m = -1800

Answer:
The linear model is
v = -1800t + 20000

Slav-nsk [51]

1) Answer: -\frac{3}{2}

<u>Step-by-step explanation:</u>

f(x) = 6x⁻¹

f'(x) = -6x⁻²

     = \frac{-6}{x^{2}}

f'(-2) = \frac{-6}{(-2)^{2}}

        = -\frac{6}{4}

        = -\frac{3}{2}

*****************************************************

2) Answer: \frac{1}{4}

<u>Step-by-step explanation:</u>

f(x) = -9x⁻¹

f'(x) = 9x⁻²

     = \frac{9}{x^{2}}

f'(6) = \frac{9}{(6)^{2}}

        = \frac{9}{36}

        = \frac{1}{4}
