Question
This is Discrete Math. Please show all work and give explanations for solutions. The second image isn't a question, it's guidelines for proving. Thank you!
Common Proof Tools This list serves as a reminder of proof justifications you may use throughout the homework. We are providing the following here as hints for your homework, however, this list will not be provided on an exam 1. x is even if and only if x is even 2. x is odd if and only if x is odd 3. Multiplication is closed under integers 4. Addition is closed under integers 5. The definition of a biconditional states that p ↔ q is equivalent to p→ q^q→p 6. The list is not all inclusive and does not include other definitions learned in class and algebraic properties learned elsewhere

2. Using rules of inference, laws of logical equivalences, and other definitions taught in class, show that the hypotheses below conclude with b. Give the reason for each step as you show that b is concluded. Each reason should be the name of a rule of inference and include which numbered steps are involved, For example, a reason for a step might be "Modus ponens using #2 and #3". (Hint: You may use the definition of biconditional and the commutative law). 1) y → x 2) x^(bv ¬d) 3) x^a →→b 4) (y Vx) Ac→ d 5) y → c
