Across
- 2. / Pulling the Least Common Multiple out from the polynomial and placing it on the outside of the parenthesis to set up the distributive property.
- 4. / an equation made up of three things: numbers, variables, and operation signs such as + and -.
- 7. / A relationship between two expressions that are not equal, often written with the symbols >, >, <, and < that mean greater than, greater than or equal, less than, less than or equal, respectively.
- 10. Numbers / A number that can be written as a fraction, or as finite or repeating decimals. The square root of 2 (1.414 213 6...) is not a rational number.
- 12. Numbers / A number that cannot be expressed as a fraction.
- 13. Variables / The output number of a function. Its value depends on the given function and the chosen value(s) for the independent variable(s).
- 15. / The “x” in the data table. The number you use to solve for the answer to the equation.
Down
- 1. / A number whose value never changes. For example, 2 in 2x3 + 7 is a constant, and so are 3 and 7.
- 3. / The number part in front of the non-numerical symbol(s) in an algebraic expression, signifying multiplication. For example, the number 4 in the expression 4xy.
- 5. variables / A variable that can change its value freely and first without being affected by any other variable(s) for its value. Usually, an __________ variable is the input to a function and is normally denoted by the symbol x while y is often reserved for the dependent variable.
- 6. / The “y” in the data table. The number you get as a result of the Input.
- 8. / The general form of a linear equation is y = mx + b, which is a straight line on a Cartesian coordinate graph.
- 9. / mathematical statement that represents the equality of two expressions involving either constants, variable(s), or both. For example, 1 + 2 = 3 is an equation. So is xy =1.
- 11. Rate / When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called ___________ ___________.
- 14. / To multiply out a product to express it as a sum of a series of terms. For example, (x + 1)(x + 3) can be expanded to x2 + 4x + 3.
