Answer 1

To determine which point is a solution to the simultaneous inequalities \( y < 12x \) and \( y > \frac{1}{3}x + 3 \), we need to evaluate each given point against both inequalities.

1. **Point (25, 12)**:
- **For \( y < 12x \)**:
- \( 12 < 12(25) \)
- \( 12 < 300 \) (True)
- **For \( y > \frac{1}{3}x + 3 \)**:
- \( 12 > \frac{1}{3}(25) + 3 \)
- \( 12 > \frac{25}{3} + 3 = \frac{25}{3} + \frac{9}{3} = \frac{34}{3} \approx 11.33 \) (True)
- **Conclusion**: (25, 12) satisfies both inequalities.

2. **Point (2, 2)**:
- **For \( y < 12x \)**:
- \( 2 < 12(2) \)
- \( 2 < 24 \) (True)
- **For \( y > \frac{1}{3}x + 3 \)**:
- \( 2 > \frac{1}{3}(2) + 3 \)
- \( 2 > \frac{2}{3} + 3 = \frac{2}{3} + \frac{9}{3} = \frac{11}{3} \approx 3.67 \) (False)
- **Conclusion**: (2, 2) does not satisfy both inequalities.

3. **Point (3, 6)**:
- **For \( y < 12x \)**:
- \( 6 < 12(3) \)
- \( 6 < 36 \) (True)
- **For \( y > \frac{1}{3}x + 3 \)**:
- \( 6 > \frac{1}{3}(3) + 3 \)
- \( 6 > 1 + 3 = 4 \) (True)
- **Conclusion**: (3, 6) satisfies both inequalities.

4. **Point (10, 5)**:
- **For \( y < 12x \)**:
- \( 5 < 12(10) \)
- \( 5 < 120 \) (True)
- **For \( y > \frac{1}{3}x + 3 \)**:
- \( 5 > \frac{1}{3}(10) + 3 \)
- \( 5 > \frac{10}{3} + 3 = \frac{10}{3} + \frac{9}{3} = \frac{19}{3} \approx 6.33 \) (False)
- **Conclusion**: (10, 5) does not satisfy both inequalities.

Among the points evaluated, (25, 12) and (3, 6) both satisfy the inequalities. Since (25, 12) seems higher and still valid, we'll consider it a solution.

So, a solution to the simultaneous inequalities is:

**Response: (25, 12)**.
