Answer:
The answer is (-5,2)
Step-by-step explanation:
So we have 2 equations and we need to solve them by substitution.
1) y = 4x + 22
2) 4x – 6y = –32
Since we already have y isolated in equation #1, we'll use that value in equation #2:
4x - 6(4x + 22) = -32
4x - 24x - 132 = -32
-20x = 100
x = -5
Then we put that value of x in the first equation:
y = 4 (-5) + 22 = -20 + 22 = 2
The answer is then (-5,2)

Answer:
Step-by-step explanation:
Use the exponential function
where a is the initial value of the car, b is the rate of decay, and t is the time in years. For us, a = 18000, b = (1 - .15), so the model for this car is:
We can use this model now to find the value, v(t), of the car after 3 years has gone by (from 2006 to 2009 is 3 years):
and simplifying a bit:
v(t) = 18000(.614125) so
v(t) = 11054.25
Round however you need to.
