Answer
The correct answers are "Infinite" and "More than the number of solutions to \( 3x +13=-26 \)."
Solution
To determine the number of solutions to the inequality \( 3x + 13 < -26 \), let's solve it step by step:
1. **Solve the Inequality:**
\[
3x + 13 < -26
\]
Subtract 13 from both sides:
\[
3x < -39
\]
Divide by 3:
\[
x < -13
\]
The inequality \( x < -13 \) has **infinitely many real solutions** since there are no restrictions on how small \( x \) can be, as long as it's less than -13.
2. **Compare with the Equation \( 3x + 13 = -26 \):**
Solving the equation:
\[
3x + 13 = -26 \implies 3x = -39 \implies x = -13
\]
The equation has exactly **one solution** (\( x = -13 \)).
3. **Assess the Options:**
- **No more than 1,000:** This is incorrect because there are infinitely many solutions.
- **Infinite:** Correct, as there are infinitely many solutions.
- **13:** Incorrect; this refers to a specific number, not the number of solutions.
- **26:** Incorrect for the same reason as above.
- **More than the number of solutions to \( 3x + 13 = -26 \):** Correct, since the inequality has infinitely many solutions compared to the one solution of the equation.
**Correct Answers:**
- Infinite
- More than the number of solutions to \( 3x +13=-26 \)

Beyond the Answer
To solve the inequality \( 3x + 13 < -26 \), we first isolate \( x \) by subtracting 13 from both sides, giving us \( 3x < -39 \). Then, dividing by 3 yields \( x < -13 \). This means there are infinitely many solutions in the form of all numbers less than -13! As for the equation \( 3x + 13 = -26 \), solving this gives a singular solution of \( x = -13 \). The inequality has more solutions than the equation because it covers all values up to, but not including, -13. So, we can confidently say there are more solutions to the inequality!
