T common factor of 14 35 and 28

7. Multiply 2,5and 4 by 7 to get these answers. That's how 7 is a common factor of these numbers.

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.
