Question | Answer |
Multi-step eqautions | eqautions with more than one operation |
solve an equation | isolate the varible haveing a coefficient of 1 on one side of the equation |
equivalent equation | eqautions that have the same solutions |
Division Property of Equality | dividing each side of an eqaution by the same nonzero number produces equvilent equations |
Multiplication Property of Equality | multiyplying each side of an eqaution by the same nonzero number produces equvilent equations |
Subtraction Property of Equality | subtracting the same number to each side of an equation produces an equivelent equation |
Addition Property of Equality | Adding the same number to each side of an equation produces an equivelent equation |
inverse operation | two operations that undo each other |
identity | an eqaution that is true for all values of the varible |
inequality | a mathematical sentence formed by placing one of the symable < or > between two expressions |
Addition Propety for Inequality | For all numbers a, b, and c, the following are true: 1) if a>b, then a+c > b+c 2) a |
Subtraction Propety for Inequality | For all numbers a, b, and c, the following are true: 1) if a>b, theb a-c > b-c 2)a |
Set-bulider notation | a notation used to describe the members of a set, { } |
Division Propety for Inequality | For all numbers a, b, and c, the following are true: 1) if c is positive and a>b, then a/c > b/c 2)a |
Multipilcation Propety for Inequality | For all numbers a, b, and c, the following are true: 1) if c is positive and a>b, then a/c > bc 2)a |
