#

Not sure where to start at all…

spark flicker Sep 21, 2024, 1:57 AM

#

Use similar rules as to how you would solve a normal equation

#

Isolate x and all

#

But if you multiply or divided by a negative number flip the arrow

#

That's basically it for linear inequalities

teal coral Sep 21, 2024, 2:37 AM

#

im still confused on how to though

#

teal coral im still confused on how to though

at least try moving numbers around and see what happens

teal coral Sep 21, 2024, 2:57 AM

#

umm

#

so..

#

ig ill group these like terms together?

#

(9x+5x) and (5-7)?

#

like this?

#

is this right?

spark flicker Sep 21, 2024, 3:04 AM

#

5x-7<5+9x
-5-7<9x-5x

teal coral Sep 21, 2024, 3:05 AM

#

Ohh

#

Wait why is it -5x?

#

Because it flipped to the other side?

spark flicker Sep 21, 2024, 3:06 AM

#

Yes

teal coral Sep 21, 2024, 3:06 AM

#

Oh ok

#

Ok

#

What do I do now

spark flicker Sep 21, 2024, 3:06 AM

#

Wdym

#

Just solve it

#

-5-7<9x-5x

teal coral Sep 21, 2024, 3:07 AM

#

So -5-7?

spark flicker Sep 21, 2024, 3:07 AM

#

-12<4x

#

4x>-12

#

So x>?

teal coral Sep 21, 2024, 3:07 AM

#

Wait why do we keep the greater/less than sign in the equation?

spark flicker Sep 21, 2024, 3:08 AM

#

Wdym we're solving for the solution set

#

Ofc we keep the sign

teal coral Sep 21, 2024, 3:08 AM

#

Ohh ok

spark flicker Sep 21, 2024, 3:09 AM

#

So what'd you get

#

Wait mb it's 4x>-12

teal coral Sep 21, 2024, 3:11 AM

#

-12 and uh

teal coral Sep 21, 2024, 3:11 AM

#

spark flicker Wait mb it's 4x>-12

Oh

spark flicker Sep 21, 2024, 3:11 AM

#

So x>?

teal coral Sep 21, 2024, 3:11 AM

#

spark flicker Wait mb it's 4x>-12

Wait explain this

spark flicker Sep 21, 2024, 3:11 AM

#

-5-7=-12

#

Yea I had a brain fart fr

teal coral Sep 21, 2024, 3:11 AM

#

Lol

#

Nah like

#

Why is it

#

4x>-12 when..

#

OHHH

#

Nvm nvm I’m dumb haha

#

I was gonna ask why is it 4x is greater than -12 when 12 is clearly bigger but I forgot abt the negative sign so it means that it’s smaller haha

#

My brain almost lost it

#

Sorry

#

I*

spark flicker Sep 21, 2024, 3:13 AM

#

Alright then x>?

teal coral Sep 21, 2024, 3:14 AM

#

How does X have a value?

#

If..

#

Where do we get tht from

#

9x and 5x?

spark flicker Sep 21, 2024, 3:15 AM

#

No if 4x is greater than - 12

teal coral Sep 21, 2024, 3:15 AM

#

Isn’t x at default 1?

spark flicker Sep 21, 2024, 3:15 AM

#

What x is greater than

teal coral Sep 21, 2024, 3:15 AM

#

spark flicker No if 4x is greater than - 12

-12*

spark flicker Sep 21, 2024, 3:16 AM

#

Yea

teal coral Sep 21, 2024, 3:16 AM

#

X> 0?

spark flicker Sep 21, 2024, 3:16 AM

#

Nah divide by 4 cuh 😭

teal coral Sep 21, 2024, 3:17 AM

#

Ohh😭😭

#

Divide wht by 4?

#

4x?

#

Or -12

#

Or 0?

spark flicker Sep 21, 2024, 3:18 AM

#

4x>-12
x>-3

#

Divide both sides by 4

#

Do you have physical math classes

#

Or are yall doing online learning

teal coral Sep 21, 2024, 3:18 AM

#

Yes…but then again math isn’t my strong suit

#

Physical

#

I forgot everything up from 9-12th grade

#

Kinda ish…

#

But not entirely

#

Idek tbh wht I remember lol

#

Too much info to take in

spark flicker Sep 21, 2024, 3:19 AM

#

Alright then with x>-3 you can graph the solution set

teal coral Sep 21, 2024, 3:20 AM

#

Wait hold up

#

Don’t give up on me yet

spark flicker Sep 21, 2024, 3:20 AM

#

I didn't we just finished the answer

#

Just graph it now

teal coral Sep 21, 2024, 3:20 AM

#

Ohh okay

#

Umm there must be another way to do it or something

#

Cuz strangely that answer isn’t working

#

Maybe uhh

spark flicker Sep 21, 2024, 3:22 AM

#

Can I see how you entered it in

teal coral Sep 21, 2024, 3:22 AM

#

Is there another way it can be written

#

Sure

#

spark flicker Sep 21, 2024, 3:23 AM

#

Oh they said to use interval notation

teal coral Sep 21, 2024, 3:23 AM

#

Yeah

#

Wait this isn’t ..💀 ok I feel real dumb rn

spark flicker Sep 21, 2024, 3:24 AM

#

They don't teach us interval notation here but uh that's
(-3,inf) I think

teal coral Sep 21, 2024, 3:24 AM

#

K..I’ll try that

teal coral Sep 21, 2024, 3:24 AM

#

spark flicker They don't teach us interval notation here but uh that's (-3,inf) I think

Oof

#

Yayy! It worked:)

#

Thank god😭🙏

teal coral Sep 21, 2024, 3:25 AM

#

spark flicker They don't teach us interval notation here but uh that's (-3,inf) I think

It works!

spark flicker Sep 21, 2024, 3:25 AM

#

Alright
