3.2: Inequalities on a Number Line - K12 LibreTexts
WebExample 1. Find the solution to the linear inequality, -2x - 39 ≥ -15, and plot it on a number line. Solution: We will solve the problem in the following way: - 2x - 39 ≥ - 15 ⇒ - 2x ≥ 24. ⇒ 2x ≤ - 24 ⇒ x ≤ - 12. The linear inequality will be plotted on … WebSep 5, 2024 · The solution to this compound inequality is all the values of x in which x is either greater than 6 or x is less than 2. You can show this graphically by putting the graphs of each inequality together on the same number line. The graph has an open circle on 6 and a blue arrow to the right and another open circle at 2 and a red arrow to the left. flanagan center
Solving Inequalities - Math is Fun
WebDec 8, 2024 · It’s simply a horizontal line, extending infinitely in both directions. You’ll see negative numbers to the left of ???0??? and positive numbers to the right of ???0???. We’ll be graphing inequalities on number lines like this one. An inequality is like an equation, but instead of an equals sign, you’ll have one of these inequality signs: WebInequality Number Line Interval Notation; x ≤ 3 (-∞, 3] x < 5 (-∞, 5) x ≥ 2 (2,∞] ... Number Line; Real Numbers; greater than or equal to . Examples on Interval Notation. Example 1: For a person to be elected as the president, he should be a minimum of 35 years old. Give an interval representing this information. WebWhere are the numbers whose distance from zero is greater than or equal to five? Again both −5 −5 and 5 are five units from zero and so are included in the solution. Numbers whose distance from zero is greater than five units would be less than −5 −5 and greater than 5 on the number line. See Figure 2.10. flanagan center somersworth nh
