PLEASE HELP!!!!!!!!!!!! Write an equation in standard form for the circle.
A)(x + 3)2 + (y + 6)2 = 16 B)(x – 3)2 + (y + 6)2 = 16 C)(x + 3)2 + (y – 6)2 = 16 D)(x – 3)2 + (y – 6)2 = 16
@Rohangrr can u help me here?
yo!
You want it step wise
Sort out the x's and y's together and put the number on the right \[x^2 - 2x + y^2 + 6y = -10 \] Complete the squares by taking the number in front of the letter (say -2), take half of it (-1) and square it (-1 squared is 1) Add this number to the left and the right \[x^2 - 2x + 1 + y^2 + 6y + 9 = -10 + 1 + 9 \] \[x^2 - 2x + 1 + y^2 + 6y + 9 = 0 \\ (x - 1)^2 + (y + 3)^2 = 0\]
Can u do i now?
i= it
uhm im confused on where you got all those numbers from the graph???
lets make it easy
See the graph
Now sort out all the X & Y that is covered by the circle
-4 and -8 if you see the graph
that was x and y's are - -4 and -2
ok
now @sh9down45 see the equation above and solve it? isn't it easy now
good! all the best
Hope the matter I'd put up helps u
its helping, thank you im solving the prob now. thank you sooo much!!!
no problem
I got (x + 3)2 + (y + 6)2 = 16 is that right???
