Question

1. which inequality matches this graph: closed circle at 10, shading left a. x<10 b. x≤10 c. x>10 d. x≥10

Explanation:

Step1: Analyze the closed circle

A closed circle means the number is included in the solution set. So it corresponds to $\leq$ or $\geq$.

Step2: Analyze the shading direction

Shading to the left on the number - line means the values are less than the number at the circle.

Answer:

B. \(x\leq10\)
