(4;12), (5;10), (7;(1) (9;10) (10;2) (1;9), (12, 8) (12;7) (9;2) (5;2) (2; 5), (2,8), (3; 9), (4;12)

It seems you have provided a series of pairs that resemble ordered pairs, potentially representing points or coordinates in a two-dimensional space. However, there are some inconsistencies in the format (e.g., using different types of separators like commas and semicolons).

To make sense of the data, let’s first correct the pairs for consistency. I'll assume you intend to use semicolons for the ordered pairs. Here’s a cleaned-up version of the list:

1. (4;12)
2. (5;10)
3. (7;1)
4. (9;10)
5. (10;2)
6. (1;9)
7. (12;8)
8. (12;7)
9. (9;2)
10. (5;2)
11. (2;5)
12. (2;8)
13. (3;9)
14. (4;12) (repeated point)

Now, you can analyze or manipulate these points as needed for your university exam preparation. Here are a few things you might want to consider:

• Plotting the Points: You could graph these points on a coordinate plane.
• Finding Distances: You could calculate the distances between certain points.
• Identifying Patterns: Look for any patterns, such as clusters of points or relationships between them.
• Removing Duplicates: The point (4;12) is repeated; you could decide whether to keep or discard duplicates.

If you have a specific task or analysis in mind regarding these points, please provide more details!
