An integer n is even if, and only if, n equals twice some integer. An integer n is odd if, and only if, n equals twice some integer plus 1. Symbolically, for any integer, n n is even ⇔ n = 2k for some integer k n is odd ⇔ n = 2k + 1 for some integer k Prove the following statement. The difference of any two odd integers is even. Proof: Let m and n be any odd integers. By definition of odd, there are integers r and s so that m can be expressed in terms of r and n can be expressed in terms of s as follows: m = n = Write m - n in terms of r and s and factor out a 2 to obtain m - n = Now is an integer because --- Select-- v of integers are integers. Therefore, m - n = 2 ⋅ (an integer), and so m - n is … - Select-- by definition of … - Select--.

Let Q(x, y) be the predicate "If x < y then x2 < y2" with domain for both x and y being R the set of real numbers. (a) Explain why Q(x, y) is false if x = -2 and y = 1. . The conclusion is --Select-- , which is --Select--- . Thus Q(-2, 1) is a conditional statement with a ---Select--- hypothesis and a The hypothesis of Q(-2, 1) is --Select-- , which is --Select-- --Select--- conclusion. So Q(-2, 1) is false. (b) Give values different from those in part (a) for which Q(x, y) is false. 1. (x, y) =( (c) Explain why Q(x, y) is true if x = 3 and y = 8. . The conclusion is -Select-- v, which is --Select--- . Thus Q(3, 8) is a conditional statement with a ---Select-- hypothesis and a The hypothesis of Q(3, 8) is --Select-- , which is --Select-- -Select-- conclusion. So Q(3, 8) is true. (d) Give values different from those in part (c) for which Q(x, y) is true. (X,Y)= ( )
