Two or more inequalities that represent the constraints in the same situation.

• system of inequalities

• system of equations

• equations

• expressions

Answer explanation

Two or more inequalities that represent the constraints in the same situation form a system of inequalities.

All pairs of values that make the inequalities in a system true are solutions to the system. This can be represented by the points in the region where the graphs overlap.

• solutions to a system of inequalities

• system of inequalities

• system of equations

• variables

Answer explanation

Solutions to a system of inequalities are all pairs of values that make the inequalities in a system true are solutions to the system. The solutions to a system of inequalities can be represented by the points in the region where the graphs of the two inequalities overlap.

A limitation on the possible values of variables in a mode, often expressed by an equation or inequality or by specifying that the value must be an integer.

• constraint

• model

• constant of proportionality

• representation

Answer explanation

A constraint is a limitation on the possible values of variables in a mode, often expressed by an equation or inequality or by specifying that the value must be an integer.

For example, distance above the ground, d, in meters, might be constrained to be non-negative, expressed by d is greater than or equal to 0.
