Question

Which inequality will have a dashed boundary line with a shaded area above its graph?

Answer 1

Dashed means its not equal to and shaded that value is greater than the line

Answer 2

Since there is a negative number on y, you know that you'll have to multiply both sides by -1, which will change the inequality to less than.

You can also input these inequalities into Wolfram to visualize the graph if it helps.

Answer 3

ok

Answer 4

I agree with @Shadow I can't input any other info on this he gave you the whole plate basically lol!

Answer 5

Yeah the first thing I said eliminates two answer choices, and the second thing I said eliminates one xD

Answer 10

just so you dont have to scroll all the way back up lol

Answer 11

so would it be plus or minus?

Answer 12

I don't know if we are allowed to give you that answer

Answer 13

oh ok

Answer 14

ask shadow

Answer 15

as long as you dont give the direct answer you should be fine

Answer 16

@Shadow would it be plus or minus (the answer )

Answer 17

Can't give answer but of course lets elimnate multiplication and divison XD thats very obvious

Answer 18

But if you need to there is always youtube to helo with tutorials on how to solve these problems completely!

Answer 19

Dashed means we know it's not equal to. This leaves C and D.

\[2x - 9y > 2 \rightarrow -9y > -2x + 2 \rightarrow 9y < 2x - 2 \rightarrow y <\frac{ 2x -2 }{ 9 }\]
\[4x + 7y > 3 \rightarrow 7y > -4x + 3 \rightarrow y > \frac{ -4x +3 }{ 7 }\]

Answer 20

< means less than, so the shaded value will be below the line.
> means greater than, so the shaded value will be above the line.

Answer 21

Hey shadow can you help with a personal finanace class or will I have to wait for someone else??

Answer 22

Don't ask one someone elses question lol

Answer 23

im just wondering XD

Answer 24

Right now I"m doing banking
