GVMS - 7.13 Solve and Graph Inequalities

Front

What does an open circle represent when graphing inequalities?

Back

An open circle indicates that the number is not included in the solution set (e.g., x < 3).

Front

What does a closed circle represent when graphing inequalities?

Back

A closed circle indicates that the number is included in the solution set (e.g., x ≤ 3).

Front

What are two examples of solutions for the inequality x < 8?

Back

7.9 and 0.8 are valid solutions.

Front

How do you solve the inequality 3x < -9?

Back

Divide both sides by 3 to get x < -3.

Front

What is the correct solution for the inequality n < 6?

Back

The solution is n < 6.

Front

True or False: You flip the inequality sign every time you multiply or divide by a negative number.

Back

True.

Front

What is the solution to the inequality x > 5?

Back

Any number greater than 5 is a solution.

Front

How would you graph the inequality x ≤ 4?

Back

Use a closed circle at 4 and shade to the left.

Front

What is the solution to the inequality -2x > 6?

Back

Divide by -2 and flip the sign: x < -3.

Front

What does it mean if an inequality has no solution?

Back

It means there are no values that satisfy the inequality.
