- 2. a quantity whose value depends on how the independent variable is manipulated
- 8. subtracting the same number from both sides of an equation does not affect the equality
- 11. a value or values that can be put in place of a variable that makes the equation true
- 12. states that if both sides of an equation are multiplied by the same number the expressions on the both sides of the equation remain equal to each other
- 14. a type of proportion in which the ratio of two quantities stays constant
- 15. the operation that undoes what was done by the previous operation
- 16. a quantity that can be changed and is not fixed
Down
- 1. states that if the same number of value is added to both sides of an equation then the equality still holds true after addition; adding the same number on both sides of an equation does not affect the equality
- 3. a variable that represents a quantity that is being manipulated in an experiment
- 4. a fixed number that indicates the rate at which ratios increase or decrease
- 5. a mathematical statement that shows that two mathematical expressions are equal
- 6. a mathematical comparison between two numbers
- 7. the values on which mathematical operations occur in an algebraic expression
- 9. putting values where the letters are; representing a variable with a letter
- 10. states that if both sides of an equation are divided by a common real number that is not equal to 0 the quotients remain equal
- 13. a relationship between two expressions or values that are not equal to each other
