Final answer:
The relation 't s' on the real numbers is x ≥ y, which means that 't' is greater than or equal to 's'.
Step-by-step explanation:
In the given question, we are asked to determine the relation 't s' on the real numbers. The options given are:
- x > y
- x < y
- x = y
- x ≥ y
The correct answer is option 4) x ≥ y. This means that 't' is greater than or equal to 's'. In other words, 't' can be equal to 's' or greater than 's'.
