This is impossible to answer without knowing what the sets A and B contain (and what ξ even refers to - universal set?).
However, we have
(A U B)' = A' ∩ B'
so that
(A ∩ B) U (A U B)' = (A ∩ B) U (A' ∩ B') = (A U A') ∩ (B U B')
If ξ is indeed the universal set, then both A U A' = ξ and B U B' = ξ, so we end up with ξ ∩ ξ = ξ.
Wait but that is a test don't you need to look at a book or something insteadt of waiting for the answers
Answer:
y-1=-3/4(x+8)
Step-by-step explanation:
y=mx+b where m=slope and b=y-intercept,
y-y1=m(x-x1)
y-1=-3/4(x-(-8))
y-1=-3/4(x+8)
A radius is a straight line from the centre to the edge of a circle. i’m not sure about any examples sorry :/
