Question

Identify the center (x + 9)^2+ y^2= 64

Answer 1

Your Center is : (-9,0).

Answer 2

This is the form of a circle. Use this form to determine the center and radius of the circle.
(
x
−
h
)
2
+
(
y
−
k
)
2
=
r
2
(
x
-
h
)
2
+
(
y
-
k
)
2
=
r
2
Match the values in this circle to those of the standard form. The variable
r
r
represents the radius of the circle,
h
h
represents the x-offset from the origin, and
k
k
represents the y-offset from origin.
r
=
8
r
=
8
h
=
9
h
=
9
k
=
0
k
=
0
The center of the circle is found at
(
h
,
k
)
(
h
,
k
)
.
Center:
(
9
,
0
)
(
9
,
0
)
These values represent the important values for graphing and analyzing a circle.
Center:
(
9
,
