Represent Constraints (Equations, Inequalities)




 

Videos and lessons to help High School students learn how to represent constraints by equations or inequalities, and by systems of equations and/or inequalities, and interpret solutions as viable or nonviable options in a modeling context. 

For example, represent inequalities describing nutritional and cost constraints on combinations of different foods
.

Suggested Learning Targets


  • Write and use a system of equations and/or inequalities to solve a real world problem. Recognize that the equations and inequalities represent the constraints of the problem. Use the Objective Equation and the Corner Principle to determine the solution to the problem. (Linear Programming)
