Which graph represents the system of inequalities? y + 3x ≥ 2y + 4 ≥ 1/2x
Accepted Solution
A:
+ We have only check for the point O(0;0) y + 3x ≥ 2 we have 0+3x0≥ 2 is wrong, we cannot choose a) y + 4 ≥ 1/2x + We try to check the point (0;-5) for y + 3x ≥ 2 and wrong we cannot choose b) + We try to check the point (5;0) for y + 3x ≥ 2 and y + 4 ≥ 1/2x all right, so we choose d)
