LHS Algebra 1 C5 Linear Inequalities
| Term | Definition |
|---|---|
| Inequality | An open sentence that contains less than, greater than, less than or equal to, or greater than or equal to. |
| set-builder notation | A more concise way of writing a solution set |
| compound inequality | When two inequalities are considered together as a union or an intersection |
| intersection | A compound inequality that contains "and" and only true if both inequalities are true. |
| union | A compound inequality that contains "or" and is true if at least one of the inequalities is true. |
| Addition property of Inequalities | If the same number is added to each side of a true inequality, the resulting inequality is also true. |
| Subtraction property of Inequalities | If the same number is subtracted to each side of a true inequality, the resulting inequality is also true. |
| Positive Multiplication property of Inequalities | If both sides of an inequality that is true are multiplied by a positive number, the resulting inequality is also true. |
| Positive Division property of Inequalities | If both sides of a true inequality are divided by a positive number, the resulting inequality is also true. |
| Negative Multiplication property of Inequalities | If both sides of an inequality that is true are multiplied by a negative number, the direction of the inequality sign is reversed to make the resulting inequality also true. |
| Negative Division property of Inequalities | If both sides of a true inequality are divided by a negative number, the direction of the inequality sign is reversed to make the resulting inequality also true. |
