This composite figure has been divided into three rectangles. 3 rectangles stacked together. The height of all three rectangles together is 10 inches. The top rectangle is 4 inches high and 8 inches wide. The bottom rectangle is 1.5 inches high and half of the width is 4 inches. What is the area of this composite figure? 30 inches squared 32 inches squared 62 inches squared 80 inches squared

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.
