Use distributive property -6(r-8)

-6r +48

Step-by-step explanation: do -6 times r which gives you -6r next do -6 times -8 which is 48 and since it not negative anymore put addition sign .

the answer

b. they are parallel and will never intersect.

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
