I need these answered ASAP

OpenStudy (bbypanda16):

It wont let me respond to you in private messages. It says I can only respond if your my my fan. Ill try and help, but ill need a few ,ins. Okay?

OpenStudy (i_love_my_nieces):

Okay I just fanned you. Okay. But remember I need this as quick as possible cause I have a family thing

pooja195 (pooja195):

ok #2 |dw:1448134916444:dw|

OpenStudy (i_love_my_nieces):

Is is perpendicular?

OpenStudy (i_love_my_nieces):

@pooja195

pooja195 (pooja195):

Well if you isolated y in the 2nd equation you get y=4x+5/8

pooja195 (pooja195):

What does this tell you?

pooja195 (pooja195):

HINT the slopes are opposites

OpenStudy (i_love_my_nieces):

Parallel?

pooja195 (pooja195):

They don't have the same slope one is pos while the other is neg.

OpenStudy (i_love_my_nieces):

So neither

OpenStudy (i_love_my_nieces):

@pooja195

pooja195 (pooja195):

good

pooja195 (pooja195):

For#1 \[\huge y-y_1=m(x-x_1)\] where m=slope (x1,y1)

pooja195 (pooja195):

\[\huge~\rm~y-8=2(x-3)\] isolate y

pooja195 (pooja195):

Need help ?

OpenStudy (i_love_my_nieces):

Yes please

pooja195 (pooja195):

Start by distributing the 2 2 x X = 2x 2 x -3= ?

OpenStudy (i_love_my_nieces):

-6

pooja195 (pooja195):

good so y-8=2x-6 now add 8 to both sides -6+8=?

OpenStudy (i_love_my_nieces):

2

pooja195 (pooja195):

good so the line that is parallel is y=2x+2

pooja195 (pooja195):

Have you attempted #3?

pooja195 (pooja195):

I think it is missing some info

pooja195 (pooja195):

"pair" theres only 1 equation...

OpenStudy (i_love_my_nieces):

oops sorry

OpenStudy (i_love_my_nieces):

pooja195 (pooja195):

First we need to isolate y \[\huge~\rm~-2x+2x+10y=5+2x\] \[\huge~\rm~10/10y=2x/10+5/10\] \[\huge~\rm~y=1/5x+1/2\]

pooja195 (pooja195):

So compare this to the other equation and tell me what you think the answer is :)

OpenStudy (i_love_my_nieces):

How did you do that?

OpenStudy (i_love_my_nieces):

@pooja195

pooja195 (pooja195):

The stpes are there i listed it so you can tell what i did.

pooja195 (pooja195):

*steps

OpenStudy (i_love_my_nieces):

I don't know

pooja195 (pooja195):

? What don't you know?

OpenStudy (i_love_my_nieces):

How to do it... I'm sorry

pooja195 (pooja195):

No need to be sorry! First we need to isolate y \[\huge~\rm~-2x+2x+10y=5+2x\] \[\huge~\rm~10/10y=2x/10+5/10\] \[\huge~\rm~y=1/5x+1/2\]

pooja195 (pooja195):

See these steps? this is serperated into part... I already isolated y for you You need to tell me if its perpendicular,parallel, or neither.

OpenStudy (i_love_my_nieces):

I honestly think perpendicular

OpenStudy (i_love_my_nieces):

But I also think that is wrong at the same time

pooja195 (pooja195):

Perpendicular is correct because they are just the opposite of each other whenever a slope is opposite they are perpendicular

pooja195 (pooja195):

This changes the answer for #2 too

OpenStudy (i_love_my_nieces):

How? What do you mean, @pooja195 ?
