Unit 4 Equations

One-Step equations and inequalities

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 constant of proportionality
Dependent variable A variable that depends on other factors.
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
Independent variable A variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable.
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.
Solution the set of all values which, when substituted for unknowns, make an equation true.
Substitution the process of replacing a variable in an expression with its actual value.
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
