Answer:
1. The solution is the region above the line y = -x/2 - 5 and below the lines y = 2x + 10 and y = -3x - 15. (All bold)
2. The solution is the region below y = -x/2 + 5 and above the lines y = 2x/3 + 1/3 and y = -4x + 5. (All bold)
Step-by-step explanation:
1) 3x+y ≤ -15
y ≤ -3x - 15
2x - y ≥ -10
y ≤ 2x + 10
x+2y ≥ -10
y ≥ -x/2 - 5
The solution is the region above the line y = -x/2 - 5 and below the lines y = 2x + 10 and y = -3x - 15. (All bold)
2) 4x+y ≥5
y ≥ -4x + 5
2x-3y ≤ -1
3y ≥ 2x + 1
y ≥ 2x/3 + 1/3
x+2y ≤ 10
2y ≤ -x + 10
y ≤ -x/2 + 5
The solution is the region below y = -x/2 + 5 and above the lines y = 2x/3 + 1/3 and y = -4x + 5. (All bold)
