Pf: Suppose that A and B are empty sets. Since A is an empty set, the statement x∈A is false for all x, so (∀x)( x∈A ⇒ x∈B ) is true! That is, A ⊆ B. Since B is an empty set, the statement x∈B is false for all x, so Since A ⊆ B and B ⊆ Α we have A = B. johnny oxfordWebThe RHS has two factors: b − a wich is positive (since a < b) and c wich is negative. This results in a negative product, so b c − a c < 0 or equivalently b c < a c. If x > 0 and y < 0 then x ( − y) > 0 as product of positive factors. This with x y + x ( − y) = x ( y + ( − y)) = x .0 = 0. Then x y = − x ( − y) < 0. johnnyp2334 aol.comWebMay 12, 2024 · Assume that all sets are subsets of a universal set U.
