Vocabulary for Algebra I - Inequalities
Question | Answer |
---|---|
Compound Inequality p.170 | Two inequalities that are combined into one statement by the word "and" or "or" |
Equivalent Inequality p. 142 | Inequalities with the same solution. For example - x > 5 and x+2 > 7 are equivalent inequalities |
Inequality p. 136 | A mathematical expression that shows ranges of possible responses - using signs like >, <, etc. |
Intersection p. 171 | The intersection of two sets is the set of all elements that are common to both sets. For example: A = {1,2,3,4} B = {1,3,5,7,9} Intersection of A and B = {1,3} |
Solution of an Inequality p. 136 | The value or values that make the inequality true. Inequality: x+2 < 6 Solution: x < 4 |
Union p.172 | The union of two sets is the set of all elements that are in either set. A = {1,2,3,4} B = {1,3,5,7,9} Union of A and B = {1,2,3,4,5,7,9} |
Property of Inequalities - Multiplication and Division by Positive Numbers p.148 | You can multiply or divide both sides of an inequality by the same positive number, and the statement will still be true. |
Property of Inequalities - Multiplication and Division by Negative Numbers p.149 | If you multiply or divide both sides of an inequality by a negative number, you must REVERSE the inequality symbol for the statement to still be true. |
Property of Inequalities - Addition and Subtraction | You can add or subtract the same number to both sides of an inequality, and the statement will still be true. |
