Coordinate Algebra Name:__________________________ Date:___________ Class Period:____ Literal Equations Notes An _______________ is a mathematical sentence that contains an ___________ __________ (____). Example: _______________ A ________________ is an _______________ that states a _________ for the relationship between certain _______________. Example: _______________ What does ___, ___, and ___ stand for? What it means to ___________: -To solve for ___ would mean to get ____ by itself on ______ side of the equation, with no _____’s on the other side. (_______) -Similarly, to solve for _____ would mean to get ____ by itself on _______ side of the equation, with no ______’s on the other side. (________) Literal Equations: -A _____________ ________________ is an equation in which the __________________ and ______________ have been replaced by ______________. Example: ax+b = c -When ______________ literal equations and formulas, you will ______________ the same _________ as when solving ________________ equations. -You will always be given an _______ _______ or ________________ and asked to solve for a specific _________________. Example: For both equations, solve for x. Coordinate Algebra Name:__________________________ Date:___________ Class Period:____ What is similar about solving the two equations? What is different about solving the two equations? How is the solution of a literal equation useful? Example: In the distance formula, d = rt, d is _____________, r is __________ of speed, and t is ___________. How could you find t if you knew d and r? James will travel 250 miles from Savannah to Atlanta. If he drives at an average speed of 50 miles per hour (mph), how much time will he spend driving? First: Rewrite the given formula to isolate _____. Second: Substitute the given information into the ______ formula. Example: Use the information above to calculate how much time James will spend driving if he drives 250 miles at an average speed of 25 miles per hour (mph).
