So what do you want to know about it? We need more info on this.
Answer:C) x2 + y2 =45
Step-by-step explanation:
The equation of a circle in standard form is (x-h)2+(y-k)2=r2.
Since you know the center is (0,0), you can sub this is value in for h and k, then use the point (3,6) to sub in for x and y and you will find r2 =45. Hope that helps :)
Y=2
If you subtract 9-7 you get the answer 2 which makes y=2.
Your answer should be 3x-x+2=4 hope this helps..
