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.______
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.
