Answer:
3. The solution is the region below the line y = x/2 - 1, above y = -4 and towards left of x = 2. (All bold)
4. The solution is the region above the lines y = -2x/3 -7/3 and y = x/3 - 28/3 and below the line y = -x/6 - 13/3. (All bold)
Step-by-step explanation:
3) 4y ≥ -16
y ≥ -4
2x ≤ 4
x ≤ 2
x-2y ≥ 6
2y ≤ x - 2
y ≤ x/2 - 1
The solution is the region below the line y = x/2 - 1, above y = -4 and towards left of x = 2. (All bold)
4) 2x+3y ≥ -7
3y ≥ -2x -7
y ≥ -2x/3 -7/3
x-3y ≤ 28
3y ≥ x - 28
y ≥ x/3 - 28/3
x+6y ≤ -26
6y ≤ -x - 26
y ≤ -x/6 - 13/3
The solution is the region above the lines y = -2x/3 -7/3 and y = x/3 - 28/3 and below the line y = -x/6 - 13/3. (All bold)
