Answer:
A:
The decreasing value of car 1 can be represented by an exponential function and car 2 by a linear function
B:
Car 1: f(x) = 
Car 2: f(x) = 18500 - 1000x
C:
Car 1 would be $10600.40 after 9 years
Car 2 would be $9500.00 after 9 years
There is a significant difference of $1100.40 in value.

Answer:
The system of inequalities is


Step-by-step explanation:
step 1
Find the equation of the dashed line with negative slope
The line passes through the points
(0,-2) and (-2,0)
Find the slope

Find the equation of the line in slope intercept form

we have

substitute

The solution of the inequality is the shaded area below the dashed line
therefore
The equation of the inequality A is

step 2
Find the equation of the dashed line with positive slope
The line passes through the points
(0,0) and (4,1)
Find the slope

Find the equation of the line (direct variation)

we have

substitute

The solution of the inequality is the shaded area above the dashed line
therefore
The equation of the inequality B is

therefore
The system of inequalities is
