Mehek (mehek14):

What do you think?

OpenStudy (anonymous):

well have you tried plugging in the given values to see which one makes the statement true?

Mehek (mehek14):

@ceeceebabyy ?

OpenStudy (anonymous):

I don't really understand how to solve the problem :/

Mehek (mehek14):

start by ading4 on both sides 12+4?

Mehek (mehek14):

*adding*

OpenStudy (anonymous):

Its asking what values of x will make the statement true

OpenStudy (anonymous):

you can treat this like a regular equation solve for x

OpenStudy (anonymous):

16 so then it's C? right?

OpenStudy (anonymous):

@Mehek14 @Thefaceless

Mehek (mehek14):

well what does x =?

Directrix (directrix):

4x > 16 x > ?

OpenStudy (anonymous):

pretend its an equation with an equals sign and when you solve for x put the > sign back in

OpenStudy (anonymous):

what am I supposed to do with 4x > 16? I'm really bad at solving equations im sorry.

OpenStudy (anonymous):

4x>16 --->4x=16 can you solve this?

Mehek (mehek14):

divide both sides by 4

OpenStudy (anonymous):

4x=16 ---> x=16/4=4

OpenStudy (anonymous):

I got 1 and 4. so is 1 x?

Mehek (mehek14):

how did you get 1? 16/4 = 4 you are correct about that

OpenStudy (anonymous):

yu said divide both sides by 4. I divided 4 by 4 and got 1. I divided 16 by 4 and got 4. so is it A? @Mehek14

Mehek (mehek14):

you don't need the one bcause x = 1

OpenStudy (anonymous):

so its A?

Mehek (mehek14):

and yes it is A

OpenStudy (anonymous):

okay thank you so much! @Mehek14

Directrix (directrix):
