OpenStudy (anonymous):

Sorry guys, my internet has been screwy all day

OpenStudy (anonymous):

idk sorry @Butterfield1215

OpenStudy (butterfield1215):

I have no IDEA

OpenStudy (anonymous):

1) what is parabola?

OpenStudy (welshfella):

y^2 + 4x - 8y - 4 = 0 (y - 4)^2 - 16 + 4x - 4 = 0 (y - 4)^2 = -4x + 20 (y - 4)^2 = -4(x - 5)

OpenStudy (welshfella):

do you see where i got the -16 from on the second line?

OpenStudy (anonymous):

4^2

OpenStudy (welshfella):

yes

OpenStudy (anonymous):

So the second one is the same way?

OpenStudy (welshfella):

yes

OpenStudy (welshfella):

you have y^2 + 6y so you start with (y + 3)^2

OpenStudy (anonymous):

And then I'm thinking that the answer is B

OpenStudy (welshfella):

yes

OpenStudy (anonymous):

C and A?

OpenStudy (welshfella):

No not C its D

OpenStudy (welshfella):

OpenStudy (anonymous):
