I need these asap
What are the classifications of each system?
1. x + 5y = - 2
x + 5y = 4
2. y = 3x + 4
- 2x + y = 4
3. y = - x + 3
2x + 2y = 6
4. 5x + 2y = - 4
5x - 2y = 3
A.
consistent independent
B.
coincident
C.
inconsistent

Well, one at a time - Inconsistent.
Has no solution. Let me go through and solve each of these.

- sloppycanada

A = inconsistent.

did you mean number one is inconsistent you put a

- sloppycanada

Sorry yeah.

- anonymous

k just take your time solving them im in no rush i just suck at math lol

- sloppycanada

Wait, you have four problems and only three types of problems.

- anonymous

you can use the abc more than once

- anonymous

you can use the answer choices more than once

- sloppycanada

I have never heard of that first one, consistent independent. I'm sorry, not sure i can help you out.

@FaireGaming

- zzr0ck3r

A means every ordered pair (x,y) is a solution
B means there is one solution
C means there are no solutions

- zzr0ck3r

Do you know how to solve systems of linear equations?

- anonymous

i already knew that my brain wont let me figure out which one is which and yes

- anonymous

@FaireGaming

- zzr0ck3r

that is all you need to do.
What do you get when you solve the first one?

- anonymous

give me one sec to solve it

- anonymous

i take that back i dont know how to solve it im completely confused

- zzr0ck3r

ok lets do the first one

- anonymous

i really dont mean to be rude but its 1 am and i have to go to sleep soon

- zzr0ck3r

x+5y=-2
Solve this for x
x=-2-5y
Now plug this in to the second equation for x
x+5y=4 becomes -2-5y+5y=4 and we get -2=4
Since this makes no sense, it is inconsistent

- zzr0ck3r

that is not rude....

- anonymous

im so confused that makes no sense

- zzr0ck3r

so if you get something like -2=4 it is inconsistent
if you get something like 2=2 it is consistent
if you get something like y=3 or x=5 then it is linearly consistent

- zzr0ck3r

which part?

- anonymous

i think i got it

- zzr0ck3r

try the second one

- zzr0ck3r

notice that the first equation for part 2 is already solved for y, so just plug it in for y in the second equation

- zzr0ck3r

simplify and tell me what you get

- anonymous

so the answer is 1a 2b 3b 4 c does that sound right thats what i got when i tried it

- anonymous

does that sound right?

- zzr0ck3r

no, and I find it very hard to believe you did all 4 systems in one minute

- zzr0ck3r

I teach this class and I could not...

- zzr0ck3r

If you take the time to do what I am showing you will spend much less time then trying to get me to give you answers. Sorry if that sounded rude :)

- anonymous

im really sorry its just im really tired and i have dyslexia so my head mixes up all the numbers so math is really hard for me

- anonymous

1 is c right did i do that right or am i still wrong i really am trying

- anonymous

@zzr0ck3r

- zzr0ck3r

correct

- zzr0ck3r

for the second one
take the first equation that says y=-x+3
and plug that into the equation below it for y, in other words replace y in the second equation with -x+3
tell me what you have after you do that

- anonymous

those numbers are for the 3rd one i thought we where doing the second one

- anonymous

oh crap its 130 am im getting in trouble because im not asleep i gotta go this sucks i didnt finish @zzr0ck3r

- zzr0ck3r

do the same things for the second one

- anonymous

i cant i have to go to sleep my moms yelling at me

- zzr0ck3r

ok good night. stop by tomorrow and we can complete it

- Liv1234

@ashley011802 Maybe you shouldn't wait to do your school work until 1 am, no offense.

- zzr0ck3r

well, it could be the case that she had been working on it all night.

- zzr0ck3r

I hope :)

- anonymous

thats the problem it was due tonight i do online school now im gonna fail it because i have to go to sleep and i was doing it al day @Liv1234 stay out of it

- Liv1234

True, but still.

- zzr0ck3r

since you said you had to go to sleep you could have solved this 3 times

- Liv1234

Please don't be rude, I was just simply stating, I'm already dealing with the death of a friend from yesterday, I do online school too and I know it can be stressful.

- anonymous

no i cant i metaly cant with dyslexia

- zzr0ck3r

I have dyslexia and I teach math at university

- anonymous

@zzr0ck3r your being really rude to me im not you

- zzr0ck3r

how is that rude?

- zzr0ck3r

I am saying that you have spent at least 20 minutes now saying that you dont have time to do the problem

- Liv1234

The point is, is that you shouldn't wait this late to do your work. If you do Connections Academy, they don't fail you for having late work.

- zzr0ck3r

lets not argue over old things

- zzr0ck3r

math is why we are hear

- zzr0ck3r

I really am dyslexic also, I had to take special classes growing up for it

- anonymous

i dont i do a private online school and if its not turned in by the dead line they fail you and ive been doing school work all day i didnt wait

- zzr0ck3r

do you understand that we could be doing the math right now instead of talking about this?

- anonymous

hey sorry my mom said i really have to get off or shes taking my computer away

- zzr0ck3r

ok then
