Math 10 Chapter 9 - Part B


1. The relation free from 'x' for equations x | 1/ x= m and x3 | 1/x3 = 4n3 is __________.



2. The relation free from 'x' for equations x = 3p and x = 1/7t is __________.




3. The relation free from 'y' for equation y2 | 1/y2 = a and y4 + 1/y4 = b4.



4. If x + y= 0 and x2 + y2 = b2 , then the relation free from x is y2 = b2


5. If x = at and y = 2at then the relation free from t is 2x = y


6. For equations x + n= 6 and x + m = 3 the relation free from x is n | m = 3.


7. One equation is required for elimination of one variable.


8. The relation free from 'x' for equations 2x + 3y = 5 and x | y = 2 is 5y =1


9. An independent relation of 'x' for equation nx2-m=0 and px2 + q = 0 is mp = qn


10. If x-y = t and x2 + y2 = t2, then relation free from t is xy = 2


11. If x/c + c/x = 2a and x/c | c/x = 3b, then relation free from x is 4a2 | 9b2 = 4


12. The eliminant by eliminating 'x' for equation x | pq = 0 and x/n = m is pq+ nm = 0


13. If x | 1/x = 3a and x2 + 1/x2 = b2 then relation free from x is b2 | 9a2 = 2


14. If x + 1/x = n and x2 + 1/x2= m2 then independent relation of x is n2 = m2 + 2


15. Independent relation of 't' for equations at = x and 2at = y is x = y


16. If x + a = 0 and b/x = c then relation independent of x is b + ac = 0


17. If x/a + a/x = 7 then x2/a2 + a2/x2 = 49


18. Eliminating t from x + t = 6 and y | t = 7 we get x + y = 1


19. Elimination means to eliminate a certain variable


20. After doing elimination process, the equation obtained is always quadratic .
