Answer:
534,070.75 miles
Step-by-step explanation:
The circumference formula is 
or 
.
But since we're given the diameter, 170,000, all we have to do is multiply it by 
.
The answer is 4/5 because if you multiply the top and bottom by 4 you get 16/20
As you see in the picture, there are two lines that could maybe represent two linear functions. However, this is not true because of the solid point and the hollow point. This is an inequality equation that has points of discontinuity.
Points of discontinuity are breaks in the graph that are a result of an undefined point when the f(x) is substituted with a point of x that is not part of the solution. So, technically, the graph is made from one rational expression.
So, when it says f(-2), this is the y-value at x=-2. That means f(-2)=2, f(0)=3 and f(4)=-1. Specifically, there are two points at x=0, but we take the solid point only.
