Answer:
A. j > 11
B. x ≥ 8
Step-by-step explanation:
For A if 7j is greater than 77, then j has to be more than 11. 7 x 11= 77.
For B x has to be greater or equal to 17, and 8+9 is equal to 17.
Answer:
Linear
Step-by-step explanation:
The balances each go up by $110
300 + 110 = 410
410 + 110 = 520
520 + 110 = 630
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.
