Prove or give a counterexample: For any integers b and c and any positive integer m, if b ≡ c (mod m) then b + m ≡ c (mod m).
Give a proof or counterexample, whichever is appropriate. 1. For any sets A and B, (A ∩ B = ∅) AND (A ∪ B = B) ⇒ A = ∅ 2. An integer n is even if n2 + 1 is odd. 3. The converse of the assertion in exercise 62 is false. 4. For all integers n, the integer n2 + 5n + 7 must be positive. 1.65. For all integers n, the integer n4 + 2n2 − 2n...

Prove or give a counterexample to the following statement: If the coefficient matrix of a system of m linear equations in n unknowns has rank m, then the system has a solution.
3. Let a, b, c E Z such that ca and (a,b) = 1. Show that (c, b) = 1. 4. Suppose a, b, c, d, e E Z such that e (a - b) and e| (c,d). Show that e (ad — bc). 5. Fix a, b E Z. Consider the statements P: (a, b) = 1, and Q: there exists x, y E Z so that ax + by = 1. Bézout’s lemma states that: if P, then...
Please only answer questions a, d, and f. Thank you. 1. True/False Explain. If true, provide a brief explanation and if false, provide a counterexample. Choose 3 to answer, if more than 3 are completed I will pick the most convenient 3. Given a sequence {an} with linn→alanF1, it follows that linnn→aA,-1. b. A series whose terms converge to 0 always converges. c. A sequence an converges if for some M< oo, an 2 M and an+1 >an for all...
