Question

(x + 7) + (y + 4)2 = 16

Center:

Radius:

Answer 1

General equation

(x-h)²+(y-k)²=r²

So

• (x+7)²+(y+4)²=16
• (x+7)²+(y+4)²=4²

Center=(-7,-4)

Radius=4

Answer 2

Center: (-7, -4)

radius = 4

Step-by-step explanation:

• Equation: (x + 7)² + (y + 4)² = 16

Circle formula:

• (x - h)² + (y - k)² = r²

(h, k) denotes the center of the circle, "r is radius"

Rewrite the following equation in standard form:

• (x - (-7))² + (y - (-4))² = 4²

From this identify:

• h = -7, k = -4, radius = 4
