Find k , if the line y = 2x + k touches the circle ` x^(2) + y^(2)`
` - 4x - 2y =0 `

Find k if line y = sqrt(3)x + k touches the circle x^(2) + y^(2) = 16.

If y = 2x + k " touches " x^(2) + y^(2) - 4x - 2y = 0 , then k=

If x + y+ k =0 touches the circle x ^(2) + y^(2) -2x -4y + 3 =0, then k can be

If x + y+ k =0 touches the circle x ^(2) + y^(2) -2x -4y + 3 =0, then k can be

If the line 3x - 4y - k = 0 (k gt 0) touches the circle x^(2)+y^(2)-4x-8y-5 =0 at (a, b) then k + a + b is equal to :-

If line 4x + 3y + k = 0 " touches circle " 2x^(2) + 2y^(2) = 5x , then k =

For what value of k will the line 4x + 3y + k = 0 touch the circle 2x^(2) + 2y^(2) = 5x

Find the value of k for which the line x + 2y + k = 0 touches the circle x ^2 + y ^2 = 5.

If 2 y+x+3=0 touches the circle 5 x^(2)+5 y^(2)=k then k=

If the straight line 3x + 4y = k touches the circle x^(2) + y^(2) = 16 x , then the values of k are
