Astore manager set up a cardboard display to advertise a new brand of perfume. the display is a square pyramid whose base is 18 inches on each side. the height of each triangular face of the pyramid is 12 inches. how much card word was used to make the display? a. 516 b.756 c.612 d.1080 d is not the answer i tried the teacher marked it wrong

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
