Let a and b be subsets of r. (a) if x ∈ (a ∩ b)c, explain why x ∈ ac ∪ bc. this shows that (a ∩ b)c ⊆ ac ∪ bc. 12 chapter 1. the real numbers (b) prove the reverse inclusion (a ∩ b)c ⊇ ac ∪ bc, and conclude that (a ∩ b)c = ac ∪ bc. (c) show (a ∪ b)c = ac ∩ bc by demonstrating inclusion both ways.

The description below represents function a and the table represents function b: function a the function is 5 more than 3 times x. function b x y −1 2 0 5 1 8 which statement is correct about the slope and y-intercept of the two functions? (1 point) their slopes are equal but y-intercepts are not equal. their slopes are not equal but y-intercepts are equal. both slopes and y intercepts are equal. neither slopes nor y-intercepts are equal.
