Question 20

Solve the system of inequalities.

Accepted Answer

The solution set for the system of inequalities is the shaded region where the two shaded regions from each inequality overlap. This region is only present in choice A. In choices B and C, the shaded region for one of the inequalities is outside of the grid, so it cannot be part of the solution set. Choice D means that there is no overlap between the two shaded regions, so there is no solution.
