Answer:
The ordered pair is a solution.
Step-by-step explanation:
Plug x = -3 and y = 0 into the 2 inequalities and see if they fit:
-2x + 2y >= 4
-2(-3) + 2(0) = 6 which is > 4 so this one fits.
y>= 2x - 6
0 >= 2*-3) - 6 = -12 which also fits.
Answer:
4x -2y + 8z
Step-by-step explanation:
10 / 4 = 4x
-5y / 2.5 = -2y
20z / 2.5 = 8z
resulting in 4x -2y + 8z.
