In this lesson, you will learn how similar the solving processes are.To graph a vertical line that goes through a given point, first plot that point.Then draw a straight line up and down that goes through the point, and you're done!In this tutorial you'll learn what an inequality is, and you'll see all the common inequality symbols that you're likely to see :) Knowing the definition for a compound inequality is one thing, but being able to identify one in a word problem or phrase can be an entirely different challenge.Arm yourself by learning some of the common phrases used to describe a compound inequality and an absolute value inequality.As a member, you'll also get unlimited access to over 79,000 lessons in math, English, science, history, and more.Plus, get practice tests, quizzes, and personalized coaching to help you succeed.Remember, flip the inequality symbol whenever you divide or multiply by a negative number.Graphing linear inequalities requires a few more steps than graphing linear equations.Recall that a linear equation has variables to the first degree only, and the variables are never squared, cubed, or taken to any other power.Your linear equations might have looked something like these: So, linear inequalities only have variables to the first power and have inequality symbols. Think back to when you last solved a linear equation. If you were given a problem such as x 2 = 6, you most likely looked at it and realized that you need to move the number 2 to the other side of the equation so that your variable is alone.


Comments Equations Inequalities And Problem Solving

  • Solving Simultaneous Equations Equations And Inequalities -

    Solving simultaneous equations EMA38 Up to now we have solved equations with only one unknown variable. When solving for two unknown variables, two equations are required and these equations are known as simultaneous equations. The solutions are the values of the unknown variables which satisfy both equations simultaneously.…
