The inequality 5x - 2y 1 > 0 is satisfied by point (-2, -1). true false
2 answers:
Answer: Hello there!
the inequality is (i think):
5x - 2y + 1 > 0
and we wanna see if the point (-2, -1) satisfies this inequality.
If we want to see it, we just need to replace the values x= -2, y = -1 in the inequality and see if it is satisfied:
5x - 2y + 1 > 0
5*(-2) - 2*(-1) + 1 > 0
-10 + 3 > 0
-7 > 0
this is false; then the point (-2, -1) does not satisfy the inequality.
2y < 5x + 1
y < 5/2x + 1/2
x = - 0.2
y = 1/2
the point is false
