## hba 3 years ago Which of the statements below are true about the graphs of the eqn x^2+y^2=9 and (x+6)^2+y^2=16? (I) both graphs are circles (ll)The two graphs touches at one point (iii)The two graphs have two distinct points of intersection @waterineyes @hartnn

1. hartnn

i am fed up of circles now....

2. waterineyes

Do you know the equation of circle center of which is at origin(0,0) ??

3. hba

I am going to start straight line after this @hartnn

4. hba

x^2+y^2=r^2 @waterineyes

5. hartnn

just lines or pair of lines ?

6. waterineyes

@hartnn will help you now.. I am shutting down you @hba and my PC. Good Night guys..

7. hba

Omg :(

8. hba

9. hartnn

i was going to say same thing....

10. waterineyes

(x+6)^2+y^2=16? here also center is (-6,0)

11. hba

Yeah so .....

12. hba

they touch at one point ok

13. waterineyes

So, Good Night..

14. hba

nooooooooooooo

15. hba

But the both of them are circles ?

16. hba

So it can be 1 and 2 ?

17. hba

I mean 1 and 3 ?

18. waterineyes

19. hba

Waiting

20. waterineyes
