Solving an absolute value inequality
WebSolving Absolute Value Inequalities. As we know, the absolute value of a quantity is a positive number or zero. From the origin, a point located at [latex]\left(-x,0\right)[/latex] has an absolute value of [latex]x[/latex] as it is x units away.Consider absolute value as the distance from one point to another point. WebNov 28, 2024 · An absolute value inequality is a combination of two concepts: absolute values and linear inequalities. Therefore, to solve an absolute value inequality, you must use the problem-solving methods of each concept. To solve an absolute value equation, use the definition. If d= x−a , then x−a=d OR x−a=−d. To solve a linear inequality, use ...

WebWe have the absolute value of 2r minus 3 and 1/4 is less than 2 and 1/2, and we want to solve for r. So right from the get go we have to deal with this absolute value. And just as a bit of a review, if I were to say that the absolute value of x is less than, well let's just say, less than 2 and 1/2, that means that the distance from x to 0 is less than 2 and 1/2.

WebMay 4, 2024 · So, you need to find out what value for x will make this expression equal to 15 as well as what value for x will make the expression equal to -15. Solving the two equations you get: x + 5 = 15 or x + 5 = − 15 − 5 − 5 − 5 − 5 x = 10 or x = − 20. You can check these two solutions in the absolute value equation to see if x = 10 and x ... WebFour (4) Cases to Consider When Solving Absolute Value Inequalities. CASE 1: CASE 2: CASE 3: The absolute value of any number is either zero (0) (0) or positive which can never be less than or equal to a negative number. The answer to this case is always no solution.
WebStep 1. Isolate the absolute value expression. It is isolated. Step 2. Write the equivalent compound inequality. 2 x − 3 ≤ −5 or 2 x − 3 ≥ 5 2 x − 3 ≤ −5 or 2 x − 3 ≥ 5. Step 3. Solve the compound inequality. 2 x ≤ − 2 or 2 x ≥ 8 2 x ≤ − 2 or 2 x ≥ 8. WebIn order to "undo" the absolute value signs, we could either get a positive or negative value, since the absolute value of \( - 5 \) is the same as the absolute value of \( 5 \), which is \( 5 \). This becomes a method where we have multiple cases. The main steps (for dealing with linear/multiple linear absolute value inequalities) are
WebTo solve inequalities with absolute values, use a number line to see how far the absolute value is from zero. Split into two cases: when it is positive or negative. Solve each case with algebra. The answer is both cases together, in intervals or words.
