Q. Solve for z. −2∣z∣<−6Write 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 are given the inequality −2∣z∣<−6. The first step is to isolate the absolute value expression by dividing both sides of the inequality by −2. Remember that when we divide or multiply both sides of an inequality by a negative number, we must reverse the direction of the inequality sign.−2∣z∣<−6∣z∣>3
Consider absolute value definition: Now that we have ∣z∣>3, we need to consider the definition of absolute value. The absolute value of a number is the distance of that number from zero on the number line, regardless of direction. Therefore, ∣z∣>3 means that z is more than 3 units away from zero. This leads to two cases: z>3 or z<−3.
Compound inequality solution: The compound inequality that represents the solution to ∣z∣>3 is z>3 or z<−3. This is because z can be either greater than 3 or less than −3 to satisfy the original inequality.
