Which two equations from the table could be used to determine the values of a and c?

Back

The equations IV and V could be used.

Front

What inequality describes the amount of money, a, Terri can spend on each person if she has a budget of $750, with $200 for room rental and 40 attendees?

Front

What does the term 'inequality' mean in mathematics?

Back

An inequality is a mathematical statement that compares two expressions, showing that one is less than, greater than, or not equal to the other.

Front

Define 'solution set' in the context of inequalities.

Back

A solution set is the set of all values that satisfy a given inequality or system of inequalities.

Front

What is the significance of the slope in a linear equation?

Back

The slope indicates the steepness of the line and the direction of the relationship between the variables.

Front

How do you determine if a point is a solution to a system of inequalities?

Back

Substitute the coordinates of the point into each inequality; if all inequalities are satisfied, the point is a solution.

Front

What is the purpose of graphing inequalities?

Back

Graphing inequalities visually represents the solution set and helps identify feasible solutions.
