If the slope of the line `((x)/(a)+(y)/(b)-1)+k((x)/(b)+(y)/(a)-1)=0` is `-1` then the value of `k=?`

The equation of the line passing through the point of intersection of the straight lines (x)/(a)+(y)/(b)=1,(x)/(b)+(y)/(a)=1 and having slope zero is

IF lines (x-1)/(2) =(y+1)/(3) =(z-1)/(4) and x-3 =(y-k) /(2) = z intersect then the value of k is

The expression ( x + 2 y )^ 20 contain two terms with the same coefficient of the form k x^a ( y)^ b and k x^ (a+1) ( y)^ (b − 1) ,then the value of a is

if (1)/(ab')+(1)/(ba')=0, then lines (x)/(a)+(y)/(b)=1 and (x)/(b')+(y)/(a')=1 are

If the lines (x-1)/(k)=(y+1)/(3)=(z-1)/(4)and(x-3)/(1)=(2y-9)/(2k)=(z)/(1) intersect, then find the value of k

If (x+iy)^((1)/(3))=a+ib where x,y,a,b are real numbers such that (x)/(a)-(y)/(b)=k(a^(2)+b^(2)) then the value of k is

If the reflection of the ellipse ((x-4)^(2))/(16)+((y-3)^(2))/(9) =1 in the mirror line x -y -2 = 0 is k_(1)x^(2)+k_(2)y^(2)-160x -36y +292 = 0 , then (k_(1)+k_(2))/(5) is equal to

IF the strasighrt line (x-2)/1=(y-3)/1=(z-4)/0 and (x-1)/k=(y-4)/2=(z-5)/1 are coplanar then the value of k is (A) -3 (B) 0 (C) 1 (D) -2

If the line (x-y+1)+k(y-2x+4)=0 makes equal intercept on the axes then the value of k is

If the line (x-2)/-1=(y+2)/1=(z+k)/4 is one of the angle bisector of the lines x/1=y/-2=z/3 and x/-2=y/3=z/1 then the value of k is
