 ratio rate ellipse stretched circle relation set of ordered pairs algebra mathematics of working with variables unknown a symbol representing an unknown quantity: in algebra, analysis, etc., frequently represented by a letter from the last part of the alphabet, as x, y, or z. constant not changing or varying; uniform; regular; invariable: Inequalities will *never* use which symbol? 1. < 2. > 3. = 4. + 3. = sequence list of numbers set apart by commas origin represented by two zeros separated by a comma on a coordinate plane binomial expression that is the sum or difference of two terms arithmetic sequence sequence in which the difference between any two consecutive terms is the same together indicating addition, or the joining of two or more amounts linear function these functions appear in the Cartesian coordinate plane as a straight line direct variation relationship between two variables in which one is a constant multiple of the other permutation selection of objects in which the order of the objects matters sequence a set of numbers in a specific order cube root number that must be multiplied times itself three times to equal a given number half open interval interval that contains only one endpoint domain set of all possible values of an independent variable in a function out of divided by, in division this is divisor exponential function any function in which a variable appears as an exponent or base factorial product of a given integer and all smaller positive integers quadrant one of the four parts into which a plane, as the face of a heavenly body, is divided by two perpendicular lines, numbered counterclockwise from upper right: solution set any and all values of the variables that satisfy an equation or system of inequalities base bottom of a shape which could be a line or face of a solid coordinate of the same order or degree; equal in rank or importance. What is the following an example of? v + 2w > 21 1. Quotation 2. Equation 3. Equality 4. Inequality 4. Inequality composite number number that is a multiple of at least two numbers other than itself and one definition of absolute value the absolute value of a number is its distance from zero on a number line For example: 65 mph is a rate since the units are different. 65 miles/1 hour When you set two rates/ratios equal to each other, we call that a _____. data numerical information minus decreased by, to subtract calculate to determine or ascertain by mathematical methods; compute: coefficient a number or quantity placed (generally) before and multiplying another quantity, as 3 in the expression 3x. absolute value In order to simply mathematical expressions, the following sequence must be observed: approximate near or approaching a certain state, condition, goal, or standard. conic section family of curves including circles, ellipses, parabolas, and hyperbolas quotient comparative value of two or more numbers matrix rectangular array of numbers that can be written using brackets or parentheses combination selection of objects from a collection in which order is irrelevant determinant single number obtained from a matrix revealing properties of matrix In a proper fraction, the _____ is less than the _____. numerator consecutive integers numbers that follow each other in order from smallest to largest interval set of all real numbers between two given numbers addition process of uniting two or more numbers into one sum, represented by the plus common ratio ratio of consecutive terms in a geometric progression linear equation equation in which each term is either a constant or the product of a constant number line line representing the set of all real numbers least common multiple smallest number that is the multiple of two or more other numbers extraneous solution solution of a simplified version of an equation that does not satisfy the original equation Rates/Ratios: If a:b are of the same unit, it is called a _____.If a:b are of different unit, it is called a _____. multiplied by number is added to itself a number of times comparison property for rational numbers for any ration numbers a/b and c/d, with b>0 and d>0, 1. if a/b
