Case 1 : The expression inside the absolute value symbols is positive. Case 2 : The expression inside the absolute value symbols is negative. The solution is the intersection of the solutions of these two cases. Absolute value inequalities will produce two solution sets due to the nature of absolute value. We solve by writing two equations: one equal to a positive value and one equal to a negative value. See and . ; Absolute value inequalities can also be solved by graphing. Oct 26, 2016 · Subtract 30 from everything to get 20 – 10 ≤ a – 30 ≤ 40 – 30. You get -10 ≤ a – 30 ≤ 10 Note that the left and right side of the inequality is the same number, except that the one of the left is negative. Now we can say, | a – 30 | ≤ 10. So the answer is clearly choice D. we have that the solution of the absolute value inequality is. All real numbers greater than -12 and less than 7.

Inequalities. Inequalities are a little trickier to deal with. In these cases the same rules are followed (getting the absolute value on one side and everything else on the other side of the equation, then split into two different equations - one negative and one positive.) Because of the inequality rule of dividing or multiplying negatives, it is important to flip the sign.
20. Car Mileage Your car averages 32 miles per gallon on the highway. The actual mileage varies from the average by 5 miles per gallon. a. Write an absolute value inequality that represents the mileage range of your car.
Some of the first steps to solving a absolute value inequality is identifying if it will be AND or OR. This is told by the was the inequality sign is pointing. The sign here is a less than so it will be an AND. This is a 4 step problem.
When solving absolute value inequalities, there are two cases to consider. Case 1 : The expression inside the absolute value symbols is positive. Case 2 : The expression inside the absolute value symbols is negative. The solution is the intersection of the solutions of these two cases.
Plot the boundary points on the number line, using closed circles if the original inequality contained a ≤ or ≥ sign, and open circles if the original inequality contained a < or > sign. If you are unsure which type of circle to use, test each critical point in the original inequality; if it satisfies the inequality, use a closed circle.
