A motor car race is 500 miles long and consists of completing laps of a circular speedway that has a circumference of 2.5 miles. For which of these functions does y represent the number of miles a motor car has left to go in the race it x represent the number of laps completed by the motor car?
A. y = -2.52 - 500
B. y = -2.50 +500
C. y = 2.52 - 500
D. y= 2.52 +500

The system of equations graphed below has how many solutions? y = 2x + 2
