find the coordinates of the vertices formed by the system of inequalities.
x≤ 3
­-x + 3y ≤ 12
4x + 3y ≥ 12
a (0, 3), (4, 0), (5, 3)
b (3, 0), (0, 4), (3, 5)
c (­-3, 3), (1, 3), (0, 4)
d (3, ­-3), (3, 1), (4, 0)
2. at what point is the maximum value found in the system of inequalities graphed below for the function f(x, y) = x - 2y?
a (0, 3)
b (0, 0)
c (5, 0)
d (5, 3)
