Answer:
center = (-2, 6)
radius = 6
Step-by-step explanation:
<u>Equation of a circle</u>

(where (a, b) is the center and r is the radius)
Therefore, we need to rewrite the given equation into the standard form of an equation of a circle.
Given equation:

Collect like terms and subtract 4 from both sides:

Complete the square for both variables by adding the square of half of the coefficient of
and
to both sides:


Factor both variables:

Therefore:
- center = (-2, 6)
- radius = √36 = 6

Answer:
x = -3
y = 6
Step-by-step explanation:
3x + y = -3
x = -y + 3
3x + y = -3
3(-y + 3) + y = -3
-3y + 9 + y = -3
-3y + y + 9 = -3
-2y + 9 = -3
-2y = -3 - 9
-2y = -12
y = -12/-2
<u>y = 6</u>
x = -y + 3
x = -6 + 3
<u>x = -3</u>
