Answer:3.496408e+14
Step-by-step explanation:
2x+ 2y= 2; -4x+4y= 12
X + y= 1 ; -x+ y= 3 ==> y= 3+ x
X+ (3+x) =1
2x = 1-3= -2 ==> x= -1
Y= 2
Answer:

Step-by-step explanation:
A circle is described by an equation in the following form:
(1)
where:
is the x-coordinate of the centre of the circle
is the y-coordinate of the centre of the circle
r is the radius of the circle
For the circle in this problem, we have:
- The centre is located at (2,-8), so

- The radius is 11, so

Therefore substituting into eq(1) we find the equation of this circle:

So the correct option is option B:
