OpenStudy (wintersuntime):

anyone please be nice enough to help me

OpenStudy (baygurl269):

ok so do you know what the question is asking?

OpenStudy (baygurl269):

@wintersuntime

OpenStudy (wintersuntime):

I dentify which of the given points are solution to the following linear equations

Directrix (directrix):

Is this the question?

OpenStudy (wintersuntime):

yes

Directrix (directrix):

To help you get started, take the given equation and fill in 2 for x and 4 for y and see if you get a true result. 3x + 2y = 12 3*2 + 2*4 = 12 ? yes or no @wintersuntime

Directrix (directrix):

Does 6 + 8 = 12 ?

OpenStudy (wintersuntime):

no

Directrix (directrix):

Correct, so cross off option A as not being an answer.

OpenStudy (wintersuntime):

for b is no

Directrix (directrix):

3x + 2y = 12 Substitute 3 for x and 2 for y and see if a true statement results.

Directrix (directrix):

Post what you get, okay?

OpenStudy (wintersuntime):

Its c and d

OpenStudy (wintersuntime):

@Directrix

OpenStudy (wintersuntime):

I also did number 2 but im struggling with number 3.

Directrix (directrix):

I agree with those answers for #1.

OpenStudy (wintersuntime):

For number 2 its a and c

OpenStudy (wintersuntime):

im struggling with number 3

Directrix (directrix):

x + y = 6 and (2,?) means that you are to substitute 2 for x and then crank out the value of y.

Directrix (directrix):

2 + y = 6 y = ?

OpenStudy (wintersuntime):

4?

OpenStudy (wintersuntime):

is that right ?

OpenStudy (wintersuntime):

so would it be A.(2,4) and B(0,6) and c (6,0)

OpenStudy (wintersuntime):

@Directrix

OpenStudy (wintersuntime):

hello?

OpenStudy (wintersuntime):

@Directrix

Directrix (directrix):

Yes, (2,4). Sorry that I was late in responding.

Directrix (directrix):

Hold on a sec while I check B and C

Directrix (directrix):

That is what I got. >>> and B(0,6) and c (6,0)

OpenStudy (wintersuntime):

okay

OpenStudy (wintersuntime):

its okay

OpenStudy (wintersuntime):

for number 5. i dont get c

Directrix (directrix):

Look at the top of the thead and meet my friend, Wolf 1728. He is an excellent helper!

OpenStudy (wolf1728):

Hello wintersuntime

OpenStudy (wintersuntime):

hi

OpenStudy (wintersuntime):

can you help me with number 5 with letter c please

OpenStudy (wolf1728):

Okay if I can find it.

OpenStudy (wintersuntime):

its on page 9

OpenStudy (wintersuntime):

Did you find it ?

OpenStudy (wintersuntime):

5. 3x-y=8

OpenStudy (wolf1728):

page 9 question 3?

OpenStudy (wintersuntime):

no question 5

OpenStudy (wolf1728):

okay question 5

OpenStudy (wintersuntime):

yes

OpenStudy (wintersuntime):

i dont get letter c

Directrix (directrix):

the problems, I think

OpenStudy (wintersuntime):

for a i got (2,-2) b (0,-8) c ( , 0) i dont know whats for c ?

OpenStudy (wintersuntime):

yes for 5

OpenStudy (wintersuntime):

letter c

OpenStudy (wolf1728):

Since y=0 then you could write the equation as 3x = 8 then x=8/3

OpenStudy (wintersuntime):

so i would have to multiply 3 times 8/3 ?

OpenStudy (wolf1728):

x=2.666666...

OpenStudy (wintersuntime):

it actually equals 8

OpenStudy (wintersuntime):

8 divided by 3

OpenStudy (wolf1728):

why does it equal 8?

OpenStudy (wintersuntime):

because 3x8/3-0=8

OpenStudy (wolf1728):

8 divided by 3 = 2.66666...

OpenStudy (wintersuntime):

multiply 3 times 3/8

OpenStudy (wolf1728):

3x = 8 right?

OpenStudy (wintersuntime):

no 8/3

OpenStudy (wintersuntime):

check in your caculator 3x8/3-0=

OpenStudy (wolf1728):

3x -y = 8 y = 0 So 3x = 8

OpenStudy (wintersuntime):

yes

OpenStudy (wolf1728):

therefore x = 8/3

OpenStudy (wintersuntime):

yes

OpenStudy (wintersuntime):

so i got (8/3,0)

OpenStudy (wintersuntime):

its right ?

OpenStudy (wolf1728):

yes :-)

OpenStudy (wintersuntime):

yay

OpenStudy (wintersuntime):

now i need to do graphing ughh

OpenStudy (wintersuntime):

i did number 6 already

OpenStudy (wintersuntime):

could u be nice enough to help me still ?

OpenStudy (wolf1728):

graphing?

OpenStudy (wintersuntime):

i hope i dont bother u

OpenStudy (wintersuntime):

yes for question 6.

OpenStudy (wintersuntime):

i mean question 7.

OpenStudy (wolf1728):

I got a phone call - might be done in about 10 minutes

OpenStudy (wintersuntime):

okay

OpenStudy (wintersuntime):

its page 9 question 7

OpenStudy (wintersuntime):

Did you find it?

OpenStudy (wolf1728):

You have to make a graph of x<7 ?

OpenStudy (wintersuntime):

|dw:1444271553126:dw| i only ploted 7 because i dont know what to do next
