Question

What is (x-4)² + y² = 4​

Answer 1

It's an equation of a circle with the center (4, 0) and the radius r = 2.

Explanation:

It's an equation of a circle.

The standard form of an equation of a circle:

`(x-h)^2+(y-k)^2=r^2`

(h, k) - center

r - radius

We have:

`(x-4)^2+y^2=4\\\\(x-4)^2+(y-0)^2=2^2\Rightarrow(4,\ 0),\ r=2`
