Elena and her husband marc both drive to work. elena's car has a current mileage (total distance driven) of 15,000 and she drives 23,000 miles more each year. marc's car has a current mileage of 46,000 and he drives 9,000 miles more each year. will the mileages for the two cars ever be equal? explain.

Two numbers have a sum of -19. one number is x. what expression represents the other number?

Which equation represents a line that passes through the point (9, -4) and has a slope of 3/5?
