Modelling a fixed cost problem as an integer linear program requiresGroup of answer choicesadding the fixed costs in the objective function.using 0-1 variables.using multiple-choice constraints.using LP Relaxation.

In a linear programming (LP) problem, if the slack value for a particular constraint is negative, it indicates:Group of answer choicesThe constraint is not feasible and cannot be satisfied.The constraint is binding, and all resources are fully utilized.The constraint has surplus resources and is not fully utilized.The slack value cannot be negative; it is always positive.
