The condition of
nonnegativity requires that:

Question 13 (1 point) If
a manufacturing process takes 4 hours per unit of xy and 2 hours per unit of x2
and a maximum of 100 hours of manufacturing process time are available, then an
algebraic formulation of this constraint is:

4×7 + 2×2 2 100

O4x2 – 2×2 s 100

4×7 – 2×2 2 100

4×7 + 2×2 < 100
