we know that
The center-radius form of the circle equation is in the format
where
(h,k) is the center of the circle
r is the radius of the circle
In this problem
we have
where
the center (h,k) is the point and the radius is equal to units
therefore
the answer is
The center of the circle is the point
Answer:
1/4
Step-by-step explanation:
you have a 1/4 because there are 13 hearts in a deck and 52 divided by 13 is 4.
hope this helped :)
Your equation is:
x² + y² = 15
X - y + z = -7
x + y + z = 1
-------------------add
2x + 2z = -6
x + y + z = 1
x + y - z = 9....multiply by -1
-------------------
x + y + z = 1
-x - y + z = -9 (result of multiplying by -1)
------------------add
2z = -8
z = -8/2
z = -4
2x + 2z = -6
2x + 2(-4) = -6
2x - 8 = -6
2x = -6 + 8
2x = 2
x = 1
x - y + z = -7
1 - y - 4 = -7
-y -3 = -7
-y = -7 + 3
-y = -4
y = 4
so x = 1, y = 4, and z = -4
