Question

the inequality graphed below represents the ages, a, of players on a baseball team. which inequality represents the same ages? 10 11 12 13 14 15 16 17 18 19 20 12 < a ≤ 18 12 ≤ a < 18 12 > a ≤ 18 12 ≥ a < 18

Explanation:

Step1: Analyze left endpoint

The graph has a closed dot at 12, meaning $a$ includes 12, so $12 \leq a$.

Step2: Analyze right endpoint

The graph has an open dot at 18, meaning $a$ does not include 18, so $a < 18$.

Step3: Combine inequalities

Merge the two conditions into one inequality.

Answer:

12 ≤ a < 18
