### Instruction: help me answer this question What is the domain of the relation R = {(x, x+5): x is a prime number less than 10}?, think step by step
### Assistant:  , The answer is The relation R = {(x, x+5): x is a prime number less than 10} Prime numbers less than 10 are 2, 3, 5, and 7. So, R = {(2, 7), (3, 8), (5, 10), (7, 12)} The domain of R is the set of all first elements of the ordered pairs in the relation. Hence, Domain of R = {2, 3, 5, 7}
