Question

Use the image to answer the question.

A number line with arrows at both the ends ranges from negative 10 to 10 in unit increments. A closed circle is marked on the tick line above 1. A line is drawn from 1 toward 10 with an arrow at the end.

To determine which inequality Weston solved, we need to interpret the graph on the number line you described. The closed circle on 1 indicates that 1 is included in the solution set, and the line extending toward 10 with an arrow indicates that all numbers greater than or equal to 1 are included in the solution.

This corresponds to the inequality:

x ≥ 1

Now let's examine the given options:

  1. x - 0.5 ≤ 0.5

    • Solving for x: x ≤ 1. This would be represented by a closed circle at 1, shading to the left towards negative infinity, which does not match the graph.
  2. x + 0.5 ≥ 0.5

    • Solving for x: x ≥ 0. This would not match since the graph includes values starting from 1.
  3. x - 1 > 0

    • Solving for x: x > 1. This would be represented by an open circle at 1 and shading to the right, which does not match because the circle is closed.
  4. x + 5 ≥ 6

    • Solving for x: x ≥ 1. This is correct and matches the shaded area starting at 1.

Based on the options provided and the description of the graph, the inequality Weston solved is:

x + 5 ≥ 6.
