(x+7)2+(y+5)2 = 16
Centre of circle: (-7, -5)
Radius: 4
(-4,3)
(-4, -6)
x2 + y2 = 49
Exactly as it's stated, that equation describes a straight line, not a circle. If you take out the phrase "times 2" from both places where it's used and replace it with "squared", then the equation describes a circle, centered at (-5, 3), with a radius of 5.
It's at the point ( -5, 3 ) The general formula of a circle is given by the equation: ( x - h )2 + ( y - k )2 = r2 Where the point ( h, k ) is the center of the circle, and r is the radius of the circle. In the equation ( x + 5 )2 + ( y - 3 )2 = 25 The first group of terms isn't subtracted. Rather than x + 5, this is actually x - -5. The center of the circle, then, is the point ( -5, 3 )

It is the equation of a circle with radius of 6 and its center at the origin.
That's the equation of a circle with its center at the origin and a radius of 8.
It's at the point ( -5, 3 ) The general formula of a circle is given by the equation: ( x - h )2 + ( y - k )2 = r2 Where the point ( h, k ) is the center of the circle, and r is the radius of the circle.

I think this means (x+7)squared + (y-5)squared =4squared, which represents a circle centred at -7,+5
The center of the circle given by the equation (x - 3)2 plus (y + 2)2 = 9 is (3,-2).
Centre = (0,0), the origin; radius = 11
At the center, (x, y) = (-2, 5)
