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 ? |
$x≤5, y ≤ 10$ $2x+3y ≤ 60$ $x+2y ≤ 40$ $x^2+y ≤ 50$ |
$x^2+y ≤ 50$ |
$x^2+y≤50$ doesn't contain all the terms with degree "1" Hence its not a valid constraint. |
