Answer 3

ok now what

Answer 4

@ROMNAY is right. Desmos Graphing Calculator is very good. It automatically graphs the coordinates you type. The only thing to watch out for is that you HAVE TO put parentheses around the coordinates for it to work.

Answer 5

\[3n - 4 \le 23\]

Answer 6

You would need to solve for n.

Answer 7

Do you know how to?

Answer 8

yes

Answer 9

I am not sure whether you need to graph on a number line or on a coordinate graph.

Answer 10

Would you, by any chance. know?

Answer 11

number line

Answer 12

Okay. I can help with that.

Solve for n first

Answer 13

ok

Answer 14

what did you get?

Answer 15

hold on

Answer 16

Answer 17

it's basically like solving for n in a typical equation:
let's replace, for now, the less than or equal to sign with the equal sign
\[3n - 4 = 23\]
what would you get for n?

Answer 18

n=1

Answer 19

are you sure?
you need to isolate n so you need to get rid of 4 by doing the inverse operation of subtraction which is addition
\[3 n - 4 + 4 = 23 + 4\]
\[3n = 27\]

Answer 20

i did it wrong hold on

Answer 21

Did you get it now?

Answer 22

I am going to come back after about 20 minutes. If you can handle the question yourself, then just say so in the comment section and I will know. If you can't, then only way possible is for you to be here for twenty minutes or come back after 20 minutes if you want my help. I am pretty sure that others might help you as well :)

Answer 23

ok

Answer 24

n=3

Answer 25

not quite

we have:

3n = 27

divide both sides by 3, what do you get?
