If `x^3-2x^2y^2+5x+y-5=0` and `y(1)=1`, then (a)`y^(prime)(1)=4/3` (b) `y'(1)=-4/3` (c)`y''(1)=-8(22)/(27)` (d) `y^(prime)(1)=2/3`

3x-y=2,5x-2y=1

(1)/(3)x+y=(10)/(3),2x+(1)/(4)y=(11)/(4)

If a function is represented parametrically be the equations x=(1+(log)_e t)/(t^2); y=(3+2(log)_e t)/t , then which of the following statements are true? (a) y^('')(x-2x y^(prime))=y (b) y y^(prime)=2x(y^(prime))^2+1 (c) x y^(prime)=2y(y^(prime))^2+2 (d) y^('')(y-4x y^(prime))=(y^(prime))^2

If x^2+y^2=t-1/t and x^4+y^4=t^2+1/t^2, then x^3y (dy)/(dx)= (a) 0 (b) 1 (c) -1 (d) non of these

3x-2y=(5)/(2),(1)/(3)x+3y=(-4)/(3)

(1)/(3)x+(1)/(4)y=4,(5)/(6)x-(1)/(8)y=4

If y is a function of xa n dlog(x+y)-2x y=0, then the value of y^(prime)(0) is (a)1 (b) -1 (c) 2 (d) 0

(1)/(2(3x+4y))=(1)/(5(2x-3y))=(1)/(4),
