Answer:
A used car has a value of $15,250 when it is purchased in 2012. The value of the car decreases at a rate of 7.5% per year.
Write an exponential function that models the value of the car, y, over x years.
To the nearest cent, what will be the value of the car after eight years?
Step-by-step explanation:
Answer:
139
Step-by-step explanation:
first you need to find the x:
180= 8x + 51 + 6x - 25
180 - 51 +25 = 8x + 6x
154 = 14x
154/14 = x = 11
then you have to work out AOB:
8x +51
8(11) +51
88+51 = AOB = 139
to check your work, workout angle BOC and add both. angles together to check if you get 180:
BOC= 6x - 25
6(11) - 25
66 - 25 = 41
To check:
BOC + AOB = 180
41 +139 = 180
180 = 180
Hope this helps!

The answer is 0 because six minus six is zero so everything that is multiplied by zero is zero
replace the numbers given for x & y so
the equation becomes 3*(-3) + 2*(-4) =
3*-3 = -9
2*-4 = -8
-9 + -8 = -17
