Question:

For the problem max $Z=ax +by, x≥0, y ≥ 0, $ which of the following is NOT a valid constraint to make it a linear programming problem ?

Options:

$x≤5, y ≤ 10$

$2x+3y ≤ 60$

$x+2y ≤ 40$

$x^2+y ≤ 50$

Correct Answer:

$x^2+y ≤ 50$

Explanation:

$x^2+y≤50$ doesn't contain all the terms with degree "1"

Hence its not a valid constraint.
