Question

timed problem
score: 2/10 current time: 25.3
which inequality is represented on the line?
number line with a closed dot at 7 and arrow to the right
answer
x < 7 x > 7 x ≤ 7 x ≥ 7

Explanation:

Step1: Analyze the number line

The number line has a closed (filled) circle at 7, which means 7 is included in the solution set. The arrow is pointing to the right, indicating all numbers greater than or equal to 7.

Step2: Match with inequalities

• \( x < 7 \): Open circle at 7, arrow left. Incorrect.
• \( x > 7 \): Open circle at 7, arrow right. Incorrect.
• \( x \leq 7 \): Closed circle at 7, arrow left. Incorrect.
• \( x \geq 7 \): Closed circle at 7, arrow right. Correct.

Answer:

\( x \geq 7 \) (the fourth option: \( x \geq 7 \))
