The value of a car decreases by about 15% in the first year. How much will a car be worth after one year if its initial value was 1000? 5000? 5020? X dollars?

Results are below.

Step-by-step explanation:

Giving the following information:

Decrease in value= 15%

To calculate the value after one year, we need to use the following formula:

New value= current value/1.15

For $1,000:

New value= 1,000/1.15= $869.57

For $5,000:

New value= 5,000/1.15= $4,347.83

For $5,020:

New value= 5,020/1.15= $4,465.22

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
