1. ### need help r-2x = 14 for s?

r - 2s = 14 Solve for s: Subtract r off both sides: -2s = 14 - r Multiply both sides by -1 to avoid trouble later: 2s = r - 14 Divide by 2: s = (r - 14)/2

6. ### Prove for each r in R , Ar={(x,y): x^2 + y^2 = r^2} is a partition?

Since r^2 = (-r)^2, we can assume without loss of generality that r ≥ 0. For each fixed r ≥ 0, A(r) is a circle centered at (0, 0) with radius r. (When r = 0, then A(0) is simply {(0, 0)}.) Hence...

8. ### On R^2, we define a relation R by (a; b)R(c; d) :, a = c: Show that (i) Show that R is an equivalence relation?

R is an equivalence relation on R² follows from the fact that equality is an equivalence relation on R¹. (a; b) R (a; b) since a=a, so R is reflexive if (a; b) R (c; d) then...
