If & = {1, 2, 3, ..., 9}, A = {1, 2, 3, 4, 6, 7, 8} and B = {4, 6, 8}, then find
verify that :
(a) (An B)' = A' U B'
(b) n(A) + n(A') = n(&)
(C) n(An B) + n((ANB)') = n(&) (d) n(A - B) + n(B - A) + n(A n B) = n(A U B).

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

whatvare the choices

step-by-step explanation:

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
