Solve for z. -|z| > -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.______
Q. Solve for z. −∣z∣>−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 term: We have the inequality: -|z| > -8First, we need to isolate the absolute value term ∣z∣. To do this, we can multiply both sides of the inequality by −1. Remember that multiplying both sides of an inequality by a negative number reverses the inequality sign.-1 \cdot (-|z|) < -1 \cdot (-8)
Multiply by −1: After multiplying by −1, we get:|z| < 8This means that the value of z, regardless of its sign, must be less than 8.
Express as compound inequality: Now we need to express this as a compound inequality. The absolute value inequality |z| < 8 means that z can be less than 8 and greater than −8 at the same time.The compound inequality is:-8 < z < 8
