Exercise 7. Let x and y be real numbers. (a) Let A be the sentence “If x + y > 0, then x > 0 or y > 0.” Use Theorem 2.10 and one of De Morgan’s laws to show that ¬A is logically equivalent to “x+y > 0 and x ≤ 0 and y ≤ 0.” Be careful not to skip any steps. (Hint: To save writing, feel free to use the abbreviation “≡” for the phrase “is logically equivalent to.” It may help you to review Example 2.3.) (b) Is the sentence A in part (a) true, or is ¬A true? Explain why. (c) Let B be the sentence “If x + y > 2, then x > 2 or y > 2.” Is B true, or is ¬B true, or is it impossible to say without further information about the specific values of x and y? (Hint: Can you find specific values for x and y for which B is true? If so, give an example of such values. Can you find other specific values for x and y for which ¬B is true? If so, give an example of such values.)

Solve a formula question, or draw a diagram, analyze the code, and write the paragraph about the given image, explain the components of the image, or anything else you prefer It is possible to define the logical connectives of conjunction, disjunction, and biconditional in terms of negation and implication. In other words, we can only use the combinations of negation and implication to interpret all five connectives. Conjunction: The conjunction of two propositions, p, and q, denoted by p A q, is true if both p and q are true and false otherwise. The conjunction can be defined using negation and implication as follows: p^ q = (p⇒¬q) In other words, p ^ q is equivalent to negating the implication "if p then not q". With the information given above, can you define disjunction and biconditional only using negation (¬) and implication (→)? Hint, you can use a truth table to validate your answer. Your answer: Please draw the related architecture diagram and explain your answer.
