Q. Solve for r. 2∣r∣>8Write a compound inequality like 1<x<3 or like x<1 or x>3. Use integers, proper fractions, or improper fractions in simplest form. ______
Isolate absolute value: We have the inequality:2|r| > 8First, we need to isolate the absolute value term by dividing both sides of the inequality by 2.\frac{2|r|}{2} > \frac{8}{2}
Determine value range: After dividing, we get:|r| > 4|This means that the value inside the absolute value must be greater than 4 or less than −4.
Split into two inequalities: To express this without the absolute value, we split it into two separate inequalities:r > 4 or r < -4This is the compound inequality that represents the solution to the original inequality.
