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 if x represent the number of laps completed by the motor car? A y = -2.5x-500
B y = -2.5x+500
C y = 2.5x-500
D y = 2.5x+500

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

-12 > a

step-by-step explanation:

-12 > a

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?
