Question | Answer |
Addition Property of Equality | Adding the same number to each side of an equation produces an equivalent expression. |
Constant of proportionality | The constant value of the ratio of two proportional quantities x and y; usually written y = kx, where k is the constant of proportionality. |
Direct Proportion (Direct Variation) | The relation between two quantities whose ratio remains constant. When one variable increases the other increases proportionally. |
Division Property of Equality | States that when both sides of an equation are divided by the same number, the remaining expressions are still equal. |
Equation | A mathematical sentence that contains an equal sign. |
Inequality | A mathematical sentence that contains the symbols >, <, ≥, or ≤. |
Inverse Operation | A mathematical process that combines two or more numbers such that its product or sum equals the identity. |
Multiplication Property of Equality | States that when both sides of an equation are multiplied by the same number, the remaining expressions are still equal. |
Proportion | An equation which states that two ratios are equal. |
Subtraction Property of Equality | States that when both sides of an equation have the same number subtracted from them, the remaining expressions are still equal. |
Term | A number, a variable, or a product of numbers and variables. |
Variable | A letter or symbol used to represent a number or quantities that vary. |
