(1) If "x+y=1 and -x+y=5

The locus of the centre of the circle which makes equal intercepts on the lines x+y=1 and x+y=5 is

The equation of the straight line through the intersection of line 2x+y=1 and 3x+2y=5 passing through the origin, is:

If the equations of three sides of a triangle are x+y=1, 3x + 5y = 2 and x - y = 0 then the orthocentre of the triangle lies on the line/lines

If x^(2)y = 2x - y and |x| lt 1 , then (( y + (y^(3))/(3) + (y^(5))/(5) + ….oo))/((x + (x^(3))/(3) + (x^(5))/(5) + ……oo)) =

If x + y = 1, and x - y = 1 , then y = ?

Find the equation of the circle circumscribing the triangle formed by the lines x + y + 1 = 0, 3 x + y - 5 = 0, and 2 x + y - 4 = 0.

A plane which passes through the point (3,2,0) nd the line (x-4)/1=(y-7)/5=(z-4)/4 is (A) x-y+z=1 (B) x+y+z=5 (C) x+2y-z=1 (D) 2x-y+z=5

Equation of a straight line passing through the point of intersection of x - y + 1 = 0 and 3x + y - 5 = 0 are perpendicular to one of them is

If x and y are integers, what is x + y ? (1) 3^x = 81 (2) 5^x = (25)/(5^y)

The graphs of y=2x-5 and x + 3y=-1 intersect at
