Answer 1

To find a point that is a solution for the simultaneous inequalities \( y > -2x + 3 \) and \( y < 3x - 3 \), we can evaluate each of the provided points by substituting their coordinates into the inequalities.

1. **For the point (2, 5):**
- Check \( y > -2x + 3 \):
\( 5 > -2(2) + 3 \)
\( 5 > -4 + 3 \)
\( 5 > -1 \) (True)
- Check \( y < 3x - 3 \):
\( 5 < 3(2) - 3 \)
\( 5 < 6 - 3 \)
\( 5 < 3 \) (False)

2. **For the point (3, 6):**
- Check \( y > -2x + 3 \):
\( 6 > -2(3) + 3 \)
\( 6 > -6 + 3 \)
\( 6 > -3 \) (True)
- Check \( y < 3x - 3 \):
\( 6 < 3(3) - 3 \)
\( 6 < 9 - 3 \)
\( 6 < 6 \) (False)

3. **For the point (1, -5):**
- Check \( y > -2x + 3 \):
\( -5 > -2(1) + 3 \)
\( -5 > -2 + 3 \)
\( -5 > 1 \) (False)
- Check \( y < 3x - 3 \):
\( -5 < 3(1) - 3 \)
\( -5 < 3 - 3 \)
\( -5 < 0 \) (True)

4. **For the point (10, 5):**
- Check \( y > -2x + 3 \):
\( 5 > -2(10) + 3 \)
\( 5 > -20 + 3 \)
\( 5 > -17 \) (True)
- Check \( y < 3x - 3 \):
\( 5 < 3(10) - 3 \)
\( 5 < 30 - 3 \)
\( 5 < 27 \) (True)

Now, summarizing the results:
- (2, 5): False for the second inequality
- (3, 6): False for the second inequality
- (1, -5): False for the first inequality
- (10, 5): True for both inequalities

Thus, the point that is a solution for both inequalities is **(10, 5)**.
