Determine the relationship between set A and set B (that is A is a subset of B, B is a subset of A, A=B, A and B are disjoint) if the following is true:
1. A intersects B = B
2. A unioned with B = B
3. A intersects B = empty set
4. A unioned with B = A
5. A intersects B = A
6. A intersects B= A unioned with B
I cannot do the proper symbols on here. So here is a description:
subset: U like symbol pointing right
intersects: upside down U
unioned: U
empty set: O with a slash through it

The only solution I see is that both A and B are empty sets and of the relationships offered, that would leave only A = B, where A = { } and B = { }.
