Jacky is driving at a speed of 55 miles per hour. Let h represent the number of hours that Jacky drives at this speed. Write an algebraic expression to represent the number of miles that Jacky travels during this time. 1. 55 + h

2.55- h

3.55/h

4.55h

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
