Ответ:
Point E(4, -2): 2(4) + (-2) < 10 is true, and 2(4) - 4(-2) > 8 is also true.
Point A(-5, 4): 2(-5) + (4) < 10 is true, and 2(-5) - 4(4) > 8 is false. This narrows it down to either the first or second choices.
Point H(-4, -4): 2(-4) + (-4) < 10 is true, and 2(-4) - 4(-4) > 8 is false because it is exactly equal to 8, not greater than 8. Therefore H is not part of the solution set, and the correct answer is the 2nd choice: E, F, G.
