Determine which of the lines, if any, are parallel. explain. line a: 3y−x=6line b: 3y=x+18line c: 3y−2x=9

Isolate the variable y

Line a: 3y = x+6

            y =  1/3x + 2

Line b: 3y = x+18

            y = 1/3 x + 6

Line c: 3y = 2x+9

            y = 2/3x +3

Explanation:

Lines a and b are parallel because they have the same slope of 1/3.

step-by-step explanation:

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
