The center of a circle is at (–10, 6) and it has a radius of 4. What is the equation of the circle?
2 answers:
[x-(-10)]²+(y-6)²=4²
the answer is (<span>x + 10)^2 + (y – 6)^2 = 16</span>
The equation of circle is given by :

where,
(h,k) is the center of circle and r is radius of circle.
Now we are given :
Center (h,k) as (-10,6) and radius as 4
Plugging these values in the equation ,

So equation of circle with center at (-10,6) and radius 4 is given by:

Answer: $9.23
because you multiply 3.59 by 3 to get $10.77 which was spent then you subtract $10.77 from $20.
Substitute -3 into the equation
y = 2|x| + 3
y = 2 (3) + 3
y = 6 + 3
y = 9
