Math 10 Chapter 9 - Part D


1. If x + y = 2 and x2 + y2 = 4 then a relation free from 'x' is




2. If x/a = b and a/x = c then bc = _________________




3. Eliminating 'z' from z2 + 1/z2= n2 and z + 1/z = m we get




4. Eliminating 'z' from z | 1/z = 5a and z2 + 1/z2 = 10 we get




5. Eliminating 'm' from m2 = y/2 and m4 = 3x we get




6. Eliminating 'y' from y = 2t and y = 2s we get




7. Eliminating 'y' from y= 1/2t and y = 2s we get




8. The relation free from 't' fro t2 = 1/x and t3 = 2y is




9. The relation free from 't' for x + 2t = p and y-3t = p is




10. The eliminant by eliminating 'm' for equations m + x = 3s and m | y = -8s is




11. The relation free from 'y' for y = 2/s and y= t/2 is




12. The relation free from 'u' for u = 2/x and y= 2/u




13. The relation free from 'u' for u = 2/tand u = 1/2s is




14. at = x bt = y




15. at2 = x bt3 = y




16. a-t2 = 0 b = t3




17. ct5 = d at3 = b




18. x + t = a y+ t =b




19. x + 1/x = n x2 + 1/x2 =m2




20. x | 1/x = n x3 | 1/x3 = m3
