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 \( \frac{24}{4.8} \): \[ \frac{24}{4.8} = 5 \]

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

Now, we need to identify the correct graph corresponding to this solution.

  • The solution \( x \geq 5 \) indicates that we should have a closed point (or dot) at 5 and an arrow pointing to the right, indicating all values greater than or equal to 5.

Looking at the options presented:

  1. The first option has a closed point at 0.5 with a leftward arrow (incorrect).
  2. The second option has a closed point at 5 with a rightward arrow (correct).
  3. The third option has a closed point at 5 with a leftward arrow (incorrect).
  4. The fourth option has a closed point at 19.2 with a rightward arrow (incorrect).

Therefore, the correct graph that shows the solution \( x \geq 5 \) is the second option:

  • 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.
