Solve and Graph One-Step Inequalities Practice - A (RC)

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions and shows that one is greater than, less than, greater than or equal to, or less than or equal to the other.

Front

What does it mean to solve an inequality?

Back

To solve an inequality means to find all values of the variable that make the inequality true.

Front

What is the solution set of an inequality?

Back

The solution set of an inequality is the set of all values that satisfy the inequality.

Front

How do you graph an inequality on a number line?

Back

To graph an inequality, use an open circle for < or > and a closed circle for ≤ or ≥. Shade the region that represents the solution set.

Front

What is the difference between < and ≤?

Back

< means 'less than' and does not include the endpoint, while ≤ means 'less than or equal to' and includes the endpoint.

Front

What is the difference between > and ≥?

Back

> means 'greater than' and does not include the endpoint, while ≥ means 'greater than or equal to' and includes the endpoint.

Front

How do you isolate a variable in an inequality?

Back

To isolate a variable, perform the same operations on both sides of the inequality, just like in equations, but remember to reverse the inequality sign if you multiply or divide by a negative number.

What happens to the inequality sign when you multiply or divide by a negative number?

Back

The inequality sign reverses direction.
