Q. Solve the inequality.z−2.4≥−0.6The solution is □Graph the solution.
Isolate z: Step 1: Isolate z in the inequality z−2.4≥−0.6. Add 2.4 to both sides to isolate z. z−2.4+2.4≥−0.6+2.4z≥1.8
Check solution: Step 2: Check the solution by substituting a value greater than 1.8 for z. Let's use z=2. 2−2.4≥−0.6−0.4≥−0.6, which is true.
Graph on number line: Step 3: Graph the solution on a number line. Draw a number line, mark the point 1.8, and shade to the right, including 1.8 with a closed circle because the inequality includes equality (≥).
