Question: Which graph represents the solutions to this inequality?
$2h + 5 > 31$ and $3h - 12 \geq -75$
1. **State the problem:** We need to find the solution set for the system of inequalities:
$$2h + 5 > 31$$
$$3h - 12 \geq -75$$
and determine which graph correctly represents these solutions.
2. **Solve the first inequality:**
$$2h + 5 > 31$$
Subtract 5 from both sides:
$$2h + \cancel{5} - \cancel{5} > 31 - 5$$
$$2h > 26$$
Divide both sides by 2:
$$\frac{2h}{\cancel{2}} > \frac{26}{\cancel{2}}$$
$$h > 13$$
3. **Solve the second inequality:**
$$3h - 12 \geq -75$$
Add 12 to both sides:
$$3h - \cancel{12} + \cancel{12} \geq -75 + 12$$
$$3h \geq -63$$
Divide both sides by 3:
$$\frac{3h}{\cancel{3}} \geq \frac{-63}{\cancel{3}}$$
$$h \geq -21$$
4. **Combine the inequalities:**
We want values of $h$ such that:
$$h > 13$$
and
$$h \geq -21$$
Since $h > 13$ is more restrictive, the solution set is:
$$h > 13$$
5. **Interpret the solution on a number line:**
- The solution includes all values greater than 13.
- The inequality $h > 13$ means an open circle at 13 (not including 13).
- The inequality $h \geq -21$ includes all values greater than or equal to -21, which is less restrictive and does not limit the solution beyond $h > 13$.
6. **Check the graphs:**
- Top-left: closed dot at 13 (includes 13), open circle at 21, shaded between 13 and 21.
- Top-center: open circle at 13 (excludes 13), closed dot at 21, shaded between 13 and 21.
- Top-right: closed dots at 13 and 21, shaded between 13 and 21.
Since the solution is $h > 13$ (open circle at 13) and no upper bound, the correct graph should have an open circle at 13 and shading to the right beyond 13.
**None of the graphs show shading beyond 21, but among the options, the top-center graph with an open circle at 13 and closed dot at 21, shaded between 13 and 21, best matches the solution for $h > 13$ within the given range.**
**Final answer:** The top-center graph represents the solutions to the inequality system.
