A number line ranges from negative 10 to 10 with numbers listed in unit increments. A closed point is plotted on the number line at 0.5. A leftward arrow is marked on the number line that originates at the closed circle and goes beyond negative 10.

To solve the inequality \(4.8x \geq 24\), we start by isolating \(x\).

  1. Divide both sides by \(4.8\): \[ x \geq \frac{24}{4.8} \]
  2. Calculate \(\frac{24}{4.8}\): \[ \frac{24}{4.8} = 5 \]

So the solution to the inequality is: \[ x \geq 5 \]

This means \(x\) is greater than or equal to 5.

Now, we need to identify which graph correctly represents this solution:

  • The graph should have a closed circle at 5 (indicating that 5 is included) and an arrow extending to the right (indicating that values greater than 5 are included).

From the given options, the one that shows a closed point at 5 and a rightward arrow beyond 10 is the correct representation of the solution:

The correct choice is:

  • A number line ranges from negative 10 to 10 with numbers listed in unit increments. A closed point is plotted on the number line at 5. A rightward arrow is marked on the number line that originates at the closed circle and goes beyond 10.
