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. |
