y=2x-1
y=-x+3

I have 2 test too

Step-by-step explanation:

i hate having to do test

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

mrb

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!
