PPT-9/8/16 In solving a system of equations, when will your answer be “no solution”?

Identify the slope and yintercept Solve for y Should the boundary in 3 be dotted or solid Why Is 1 3 a solution to the inequality in 3 Why A service club is selling copies of their holiday cookbook to raise funds for a project  The printers setup charge is 200 and each book costs 2 to print  The cookbooks will sell for 6 each  How many cookbooks must the members sell before they make a profit. 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). I Can: . solve systems of equations by graphing.. What is a system of equations?. A system of equations is when you have two or more equations using the same variables.. The solution to the system is the point that satisfies . using Elimination. Steps:. 1. Place both equations in Standard Form, A. x . + B. y . = C.. 2. Determine which variable to eliminate with Addition or Subtraction.. 3. Solve for the variable left.. Systems of Equations in 3 Variables. Visualize a System of . 2 Equations of 2 variables. : . Ax + By = C. Each equation defines a . straight line. on the flat plane of an . x-y. coordinate graph. Chapter 7.3. Modeling - 2x + 3 = 11. =. Each one has 4 squares, so 4 is your answer!. Solving 2-Step Equations. Algebraic equations are solved backwards, so do the OPPOSITE math!. Since there are more than 1 steps to do you must follow the Order of Operations…but BACKWARDS!!!. 21. (. 5-. 6. ). Homework: maintenance sheet 24 & study island . . Due tomorrow!!. Unit Test Friday. Learning Target: Solving systems of equations algebraically . Homework Check 1-8. Part A. If you read from left to right . 10 . “is greater than “ . 5. . X. If you read from right to left . 5. . “is less than “ . 10. . X. If you read from left to right . 5. . “is less than “ . 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. If you read from left to right . 10 . “is greater than “ . 5. . X. If you read from right to left . 5. . “is less than “ . 10. . X. If you read from left to right . 5. . “is less than “ . 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.. Unit 4. Review:. Slope and Slope-Intercept. Slope and Slope-Intercept Form. Slope-Intercept Form. :. . . is . ______ . and . is the . __________ . of the line.. Graph is a . straight non-vertical line.
