Question

identify which of the following are solutions of the inequality z - 3 < 9 by dragging each value to the appropriate bin. keyboard help questions k solution not a solution 11 12 13

Explanation:

Step1: Solve the inequality

First, solve the inequality \( z - 3 < 9 \). Add 3 to both sides of the inequality: \( z - 3 + 3 < 9 + 3 \), which simplifies to \( z < 12 \).

Step2: Check each value

• For \( z = 11 \): Since \( 11 < 12 \), 11 is a solution.
• For \( z = 12 \): Since \( 12 \) is not less than \( 12 \) (it's equal), 12 is not a solution.
• For \( z = 13 \): Since \( 13 > 12 \), 13 is not a solution.

Answer:

• Solution: 11
• Not a solution: 12, 13
