Step-by-step explanation:
check it.. i have solved it for you.
Say x=5.764---
Then 1000x=5764.764---
Then 1000x-x = 5759
So 999x = 5759
So x=5759/999
I don't see how b can be 0 in this case... what does that mean? You would never divide by 0 and live to tell about it, right?
The equation of a circle:

(h, k) - a center
r - a radius
We have:
The center (-3, -4) → h = -3 and k = -4.
The radius is equal the distance between the center of the circle and the origin.
The formula of a distance between two points:

Substitute

therefore r = 5.
