Give the smallest equivalence relation r on a containing the pairs (a, c), (a, e), and (b, d) (i. e., the equivalence relation r containing the given pairs with the fewest number of elements). what are the equivalence classes of your relation r from part i? let s be the relation on the set of integers such that xsy if and only if x2 ≡2 y2. in other words, s = { (x, y) ∈ z × z | x2 ≡2 y2 }. show that s is an equivalence relation. what are the equivalence classes of s?

step-by-step explanation:

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
