Question

x^2+y^2+x+y-1/2=0 find the center(h,k) and radius r of each circle(B) Graph each circle(c)find the intercepts...

Answer 1

(x + 1/2)^2 - 1/4 + (y + 1/2) - 1/4 = 1/2
(x+ 1/2)^2 + (y+1/2)^2 = 1
center is (-1/2, -1/2) and radius = 1

Answer 2

wow!!! I was not even close ..... thank you so much

Answer 3

theres only one circle

Answer 4

yw

Answer 5

and that's the -1/2, -1/2

Answer 6

yes thats the coordinates of the center
do you need the x and y intercepts as well?

Answer 7

yes

Answer 8

I am terrible at math. taking a college pre calculus and feeling really dumb right notw...lol

Answer 9

(x+ 1/2)^2 + (y+1/2)^2 = 1
when y = 0
(x+ 1/2)^2 + (1/2)^2 = 1
x^2 + x + 1/4 + 1/4 = 1
x^2 + x - 0.5 = 0
x = 0.366 and - 1.366 = x- intercepts

Answer 10

y intercepts have the same values

Answer 11

best way to improve is to practice problems as often as u can - good luck

Answer 12

I will ... thank you so much
