Give a Fitch-style natural deduction proof of the sentence ∀x(P (x) ∨ ∃yQ(y)) → (∀xP (x) ∨ ∃yQ(y)).
Hint: you will need to use RAA. If it helps, you may assume you already proved
¬∀xP (x) → ∃x¬P (x) (indeed, you proved this in Problem Set 7, problem 6(c)).

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.
