Constraint

Definition

A constraint is a limitation or restriction that must be taken into account when solving a problem or making a decision. It represents a condition or requirement that must be satisfied in order for a solution to be valid or feasible.

5 Must Know Facts For Your Next Test

1. Constraints in the context of linear inequalities represent the boundaries or limits that the solution must adhere to.
2. Constraints can be represented using mathematical inequalities, such as $x \geq 0$ or $2x + 3y \leq 12$.
3. The set of all solutions that satisfy the constraints is known as the feasible region, which is the area where the optimal solution must lie.
4. Solving applications with linear inequalities involves identifying the constraints, graphing the feasible region, and then determining the optimal solution within that region.
5. Constraints are crucial in optimization problems, as they ensure that the final solution is practical and realistic given the limitations of the problem.
