PPT-Solving an Absolute Value Equation

Solving an Absolute Value Equation You have already used graphs and mental math to solve some absolute value equations For instance 8 and 8 This has two solutions Solving an Absolute Value Equation. Lesson Objective:. An equation is like a set of scales.. To keep it balanced, whatever you. do to one side you must do to the other.. Use this idea to solve equations like:. 3x + 1 = x + 7 . 2 (3x + 1) = 3 (x – 2). By: Pedro Cuellar ONLY!. The Golden Rule. Whatever you do to . one side . you do to the other.. 2X+5=15 or 5X-54=130. How would you solve the following two equations? What would be the recommended strategy to find out the answer?. (in three variables). Section 1.4 beginning on page 30. A Linear Equation in Three Variables. What Does This Look Like?. Solving Algebraically. Examples. Solve each system:. Example 1: . Example 2 : . Multiplication . Equations. 3-3 Solving . Multiplication . Equations. Solve. Solution. GOAL. Find the value of the variable that makes the. equation TRUE.. The value that makes the equation true.. To isolate the variable (have the variable on one. Equations. AII.4a – The student will solve, algebraically and graphically, absolute value equations and inequalities. Graphing calculators will be used for solving and for confirming the algebraic solution. . Solving a Problem by Creating an Equation. Toucans and blue-and-yellow macaws are both tropical birds. The length of an average toucan is about two thirds of the length of an average blue-and-yellow macaw. Toucans are about 24 in. long. What is the length of an average blue-and-yellow macaw?. (in three variables). Section 1.4 beginning on page 30. A Linear Equation in Three Variables. What Does This Look Like?. Solving Algebraically. Examples. Solve each system:. Example 1: . Example 2. : . Ch. 1.6. Absolute Value Equations and Inequalities . EQ: How can you solve absolute value equations and inequalities? I Will solve absolute value equations and inequalities. . Bell Work. Solve the inequality. Graph the solution. . Mathematical Language. A . solution. of an equation is a number that make the equation true. 3x+2=17. To . solve. an equation means to find all its solution. Two equations are equivalent if they have the same solutions. Equations Using Algebra Tiles . Objectives. Solving Equations Involving the Distributive Property. Solving Multi-Step Equations. Solving Equations. The development of the equation solving model is based on two ideas.. Solving Absolute Value . Inequalities. Situation. The Frito-Lay plant has strict standards when it comes to bagging their products. The weight of the chips in a snack-size bag must be within 0.15 ounces of the advertised size of 1.75 ounces in order to be sent to the store shelf. . How do the value of . a. , . h. , and . k. , affect the graph of the absolute value function . ?. Students will be able to translate graphs of absolute value functions.. Students will be able to . stretch, shrink and reflect graphs of absolute value functions.. Sixth. Edition. Chapter . 2. Linear Functions and Equations. Copyright © . 2018, 2014, 2010 . Pearson Education, Inc. All Rights Reserved. 2.5 Absolute Value Equations and Inequalities. Evaluate and graph the absolute value function. Katherine Wu. the . absolute value. of a number is its distance from 0 on a number line. distance is nonnegative so the absolute value of a number is always positive. symbol |x| is used to represent the absolute number of a number x.
