If no solution of `3siny+12sin^3x=a` lies on the line `y=3x ,` then `a in (-oo,-9)uu(9,oo)` a`a in [-9,9]` `a a in {-9,9}` `non eoft h e s e`

If roots of x^(2)-(a-3)x+a=0 are such that at least one of them is greater than 2 then a in[7,9] b.a in[7,oo] c.a in[9,oo] d.a in[7,9]

If ln^(2)x+3ln x-4 is non negative,then x must lie in the interval: [e,oo) b.(-oo,e^(-4))uu[e,oo) c.(1/e,oo) d.none of these

The lines 3x-4y=9 and y=0 meet at :

If x+y=k is normal to y^(2)=12x, then k is 3( b) 9(c)-9( d) -3

If |x+2|lt=9 then x in (-7, 11) b. x in [-11 ,7] c. x in (-oo,7)uu(11 ,oo) d. x in (-oo,-7)uu[11 ,oo)

If the solution of the equation (x^(4)-9)-(x^(2)+3)|=[x^(4)-9|-|x^(2)+3| is (-oo,p]uu[q,oo) then

If a point (a,2) lies between the lines x-y-1=0 and 2(x-y)-5=0, then the set of values of a is (A) (-oo,3)uu((9)/(2),oo) (B) (3,(9)/(2)) (B) (-oo,3) (D) ((9)/(2),oo)

The value of lambda for which the circles x^2 + y^2 = 1 and x^2 + y^2 - 4lambdax+8=0 have only two common tangetns, is : (A) (- 9/4, 9/4) (B) (-oo, - 9/4)] uu [9/4, oo) (C) (-oo, - 9/4] uu [9/4, oo) (D) none of these
