Answer:x=7& y= 2

Step-by-step explanation:

x+3y=13

3x+2y=25

Using elimination method

We have

3× x+3y=13......I

1×3x+2y=25....ii

3x+9y=39

3x+2y=25

7y=14

Divide through by 7

y=2

Substitute for y in equation i

x+3(2)=13

x+6=13

x=7

Identify the center and radius of the circle (x-7)^2+(y-11)^2=36
OverLord2011 [107]

Answer:

Centre is (7,11)

Radius is 6

Step-by-step explanation:

The general equation for a circle is written in the form (x-a)^2+(y-b)^2=r^2 , where (a,b) is the centre of the circle, and r is the radius.

For your circle, (x-7)^2+(y-11)=36, we can compare it with the general equation to find the centre and radius.

-a = -7

-b = -11

r^2 = 36

Therefore, a=7, b=11 and r=6.

Centre at (a,b) which is (7,11) .
