Math Problem Statement

Is (-2,10) a solution to this system of inequalites y> -1/2x+5,y<-9 yes or no

Solution

To determine if the point (-2, 10) is a solution to the system of inequalities:

  1. First inequality: y>12x+5y > -\frac{1}{2}x + 5

Substitute x=2x = -2 and y=10y = 10: y>12(2)+5y > -\frac{1}{2}(-2) + 5 10>1+510 > 1 + 5 10>6(True)10 > 6 \quad \text{(True)}

  1. Second inequality: y<9y < -9

Substitute y=10y = 10: 10<9(False)10 < -9 \quad \text{(False)}

Since the point (-2, 10) satisfies the first inequality but not the second, the answer is no, (-2, 10) is not a solution to the system of inequalities.
