can help you.

Answer 3

Hello @love_to_love_you are you sure you have the right question?
I can't seem to find a x in the f(x) = |2+1| + 5 equation

Answer 4

*2x sorry!

Answer 5

that's better, thank you :)

now f(-3) means that you plug in -3 for x
so you can get f(-3) = |2(-3)| + 5
from there... = | -6 | + 5
and remember that anything in an absolute values sign | | comes out positive
so you can get 6 + 5 = ?

Answer 6

oh wait hmmm... I don't see it listed as any of the given options...

Answer 7

I don't know why it isn't there.

Answer 8

well could you check the original questions again to see if you made any typos? :/

Answer 9

it would be d.

Answer 10

@ranbowcrazzzyyy why? :3

Answer 11

ohhhhhhhh I see
then |2(-3) + 1| + 5
= |-6+1| + 5
= |-5| + 5
= 5 + 5 =
so yes you were correct @love_to_love_you

Answer 19

slope = rise / run
as in how much it goes up over how much it goes to the right
slope = 1 = 1/1
so everytime it goes right 1 it goes up 1
slope = 2 = 2/1
so every time it goes right 1 it goes up 2
