Question

the inequality graphed represents the ages, a, of players on a baseball team. which inequality represents the same ages? 12 ≤ a < 18; 12 < a ≤ 18; 12 ≥ a < 18; 12 > a ≤ 18

Explanation:

Step1: Analyze the number line

The closed circle at 12 means \( a \) can be equal to 12 (so \( 12 \leq a \)), and the open circle at 18 means \( a \) is less than 18 (so \( a < 18 \)).

Step2: Combine the inequalities

Combining these, we get \( 12 \leq a < 18 \).

Answer:

\( 12 \leq a < 18 \) (the first option: \( 12 \leq a < 18 \))
