Answer:

$16,748

Step-by-step explanation:

we know that

The equation of a exponential decay function is equal to

y=a(1-r)^x

where

y is the value of the car

x is the number of years

a is the initial value

r is the rate of change

In this problem we have

a=\$25,000\\r=12.5\%=12.5/100=0.125

substitute

y=25,000(1-0.125)^x

y=25,000(0.875)^x

For x=3 years

substitute

y=25,000(0.875)^3=\$16,748

PLEASE I NEED HELP INSTANTLY <br> I WILL GIVE BRAINLY AND THANKS
Goryan [66]

Answer:

so you're going to need to find the slope. in order to do that use (y2-y1)/(x2-x1)

(7-(-2))/(0-8)

simplify

9/-8

simplify -9/8

now using y=mx+b, we need to find b. so we can plug in the coordinates of (0,7) or (8,-2). let's use (8,-2) because it involves more math.  

y=mx+b

-2=(-9/8)(8)+b

multiply (-9/8) by 8 to get -9

-2=-9+b

add 9 to both sides

7=b

so our equation is now

y=-(9/8)x+7

Determine if (x+1) is a factor 4x^2 + 2x - 5Use synthetic division
ikadub [295]

Given

4x^2+2x-5

Divide it by (x+1) using synthetic division, as shown below

The green line is a minus sign.

Thus,

\Rightarrow4x^2+2x-5=(x+1)(4x-2)-3

Therefore, since the remainder is different than zero, (x+1) is not a factor of 4x^2+2x-5
