WGU C955 - Module 3 Exam Questions With Correct Answers

Order of Operations - Answer A set of rules that defines the order in which mathematical operations should be performed. unlike terms - Answer Terms that do not have the same variable(s) with the same exponent(s). These terms can not be combined using addition or subtraction. ordered pairs - Answer Two numbers written in the form (x, y), where x represent the x-value or x-coordinate, and y represents the y-value or y-coordinate. equation - Answer Two mathematical expressions separated by the equals sign, =. The two expressions on either side of the equals sign hold the same value as one another. linear - Answer An expression or equation of degree 1. degree - Answer The largest exponent in an expression. horizontal line - Answer A line that runs left to right on the coordinate plane, parallel to the x-axis. It has no 'rise' or change in y-value. distributive property - Answer A mathematical principle used to multiply one term by multiple terms. This principle is employed when there are parentheses around multiple terms, which are in turn multiplied by a single term. combining like terms - Answer Combining terms that have the same variable component. Combining like terms helps to consolidate when solving an equation. quadrants - Answer The four sections of the coordinate plane, separated and defined by the x-axis and y-axis. value - Answer A number or numerical worth. the substitution method - Answer When a variable is substituted by its known value in an algebraic expression or equation. quadratic - Answer An expression or equation of degree 2. arithmetic expression - Answer A string of numbers connected by elementary operations. division principle of equality - Answer If both sides of an equation are divided by the same number, the result is an equivalent equation. y-intercept - Answer The y-value of the point at which a line intersects with the y-axis. exponent - Answer Sometimes called a power, it is a quantity that represents repeated multiplication. algebraic equation - Answer Any equation that contains variables, constants, or mathematical operations.
