Sarah has a wall hanging in the shape of a parallelogram. what is the height of the wall hanging if its area and base are 300 square centimeters and 20 centimeters respectively?

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.
