Consider the lines `x=k` and `y=k`, `k in {1, 2,......, 9)`. The number of non-congruent rectangles, whose sides are along these lines, is......

Let the line x-8y+k=0,k in l meets the rectangular hyperbola xy =1 at the points whose abscissae are integers then the number of such lines is

If two lines 2x+3y=8 and kx+4y-9=0 are lines. bot find k

If the lines x=k, k=1,2:…., n meet the line y=3x+4 at the points A_(k)(x_(k), y_(k)), k=1,2,….,n then the ordinate of the centre of Mean position of the points A_(k), k=1,2,…,n is

Find the point of intersection of the lines 4x + 3y = 1 and 3x - y + 9 = 0 . If this point lies on the line (2k - 1) x - 2y = 4 , find the value of k. The above question can also be stated as : If the lines 4x + 3y = 1, 3x – y + 9 = 0 and (2k - 1) x - 2y = 4 are concurrent (pass through the same point), find the value of k.

Two point (b+3,b+k) and (2,b) are on the line x-2y+9=0 find k

Distance of origin from the line (1+sqrt3)y+(1-sqrt3)x=10 along the line y=sqrt3x+k

Distance of origin from the line (1+sqrt3)y+(1-sqrt3)x=10 along the line y=sqrt3x+k
