Answer:
The boundaries of the region containing points that satisfy all four equations are noted on the attached image.
Explanation:
The attached worksheet illustrates the steps taken to define the boundaries of the points that solve all four inequalities. By marking each region satisfying each inequality, we can find the portion that contain solutions that satisfy all inequalities. The resulting 3-sided trapezoid has verticies at (-3,4), (0.4,4), and (4.3, -5.7).
