1. **State the problem:** Solve the compound inequality $$5k + 9 \geq 14$$ or $$-7k - 5 \geq 2$$ and graph the solution on a number line.
2. **Solve the first inequality:**
$$5k + 9 \geq 14$$
Subtract 9 from both sides:
$$5k + \cancel{9} - 9 \geq 14 - 9$$
$$5k \geq 5$$
Divide both sides by 5:
$$\frac{5k}{\cancel{5}} \geq \frac{5}{\cancel{5}}$$
$$k \geq 1$$
3. **Solve the second inequality:**
$$-7k - 5 \geq 2$$
Add 5 to both sides:
$$-7k - \cancel{5} + 5 \geq 2 + 5$$
$$-7k \geq 7$$
Divide both sides by -7 (remember to reverse the inequality sign when dividing by a negative):
$$\frac{-7k}{\cancel{-7}} \leq \frac{7}{\cancel{-7}}$$
$$k \leq -1$$
4. **Combine the solutions:**
The solution is $$k \geq 1$$ or $$k \leq -1$$.
5. **Graph the solution:**
- For $$k \geq 1$$, draw a closed circle at 1 and shade to the right (since it includes 1).
- For $$k \leq -1$$, draw a closed circle at -1 and shade to the left.
**Final answer:** $$k \leq -1$$ or $$k \geq 1$$
