Maximise $Z = 3x + 4y$ (if possible) subject to constraints $x-y≤-1,-x + y ≤0, x, y ≥0$.
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → No maximum value
We draw the lines $x - y = -1$ and $y = x$. Shade the region satisfied by the given inequations. As we can see that there is no feasible region.
∴ No maximum value of Z.
