# Writing and solving compound inequalities

Now, I like to get all my x terms on the left-hand side, so let's subtract 8x from both sides of this equation. You may be thinking, "Wow, that seems like a lot of work for one problem. Negative 7 plus 5, that's negative 2. Or we could write this in interval notation. Part one problems of the Guided Practice is much easier for students to complete than Part Two problems The greater than or equal to has to become a less than or equal sign.

But we have to remember, when you multiply or divide both sides of an inequality by a negative number, you have to swap the inequality. Air Force I This is a survey course designed to introduce students to the United States Air Force and provides an overview of the basic characteristics, missions, and organization of the Air Force.

Method 2, which I will show you next, is going to require less work because you can solve both parts of the equation at the same time. Polynomial Inequalities — In this section we will continue solving inequalities.

Factoring Polynomials — In this section we look at factoring polynomials a topic that will appear in pretty much every chapter in this course and so is vital that you understand it.

In addition, we discuss how to evaluate some basic logarithms including the use of the change of base formula. Equations With More Than One Variable — In this section we will look at solving equations with more than one variable in them. Negative 5 times 1 is negative 5, and then that's going to be greater than or equal to negative 1 plus 2 times 4x is 8x.

So let's remember that. While there is some review of exponents, factoring and graphing it is assumed that not a lot of review will be needed to remind you how these topics work. Let's say we have 5x is greater than 8x plus The left-hand side becomes 5x minus 8x.

Negative 1 minus 6, that's negative 7, and then we have this plus 8x left over. I try to have an Answer Key to enable students to check their work on the Independent Practice.Solving Inequalities Worksheets. Solving Inequalities Worksheet 1 – Here is a twelve problem worksheet featuring simple one-step inequalities. Use inverse operations or mental math to solve for x. Solving Inequalities Worksheet 1 RTF. Solving Compound Inequalities. n our last lesson, you were introduced to compound agronumericus.com this lesson, we are going to take the next step and begin solving compound inequalities. The graph shows an arrow beginning on 5 with an open circle and pointing to the left, thus that portion of the graph says, all real numbers less than 5.

There is a second arrow beginning on 9 with a closed circle and pointing to the right, representing all real numbers greater than or equal to 9. Solving Inequalities and Applications () helpful hint You can think of an inequality like a seesaw that is out of balance. 50 > 20 If the same weight is added to. Page 1 of 2 CHAPTER3 Systems of Linear Equations and Inequalities CHAPTER STUDY GUIDE Solving Linear Systems by Graphing GRAPHING CALCULATOR: Graphing.

Steps for Solving Inequalities. Solve the inequality as you would an equation which means that "whatever you do to one side, you must do to the other side".
