Add(3)/(5)and(13)/(5)

2 3/5-:5/7=\ (13)/7 (b) (13)/(25) (91)/(25) (d) (25)/(91)

Show that the point A (1,-1,3), B ( 2,-4,5) and C ( 5,-13,11) are collinear.

(-5)/(13)+?=-1 8/(13) (b) (-8)/(13) (-18)/(13) (d) (18)/(13)

The circumcentre of the triangle with vertices (1,3),(-3,5)(5,-1) is

Find the midpoint of the line joining the points (-5,7) and (-1,3).

ABC is an isosceles triangle.If the co- ordinates of the base are (1,3) and (-2,7) then co-ordinates of vertex A can be: (-(1)/(2),5) (b) (-(1)/(8),5)((5)/(6),-5) (d) (-7,(1)/(8))

The coordinates of the point where the line joining P(3,4,1) and Q(5,1,6) crosses the XY PLANE (A) (-13/5, -23/5, 0) (B) (13/5, 23/5, 0) (C) (13/5, -23/5, 0) (D) (-13/5, 23/5, 0)

The adjoint of the matrix [(2,5),(3,1)] is (A) [(2,5),(3,1)] (B) [(1,-5),(-3,2)] (C) [(1,-3),(-5,2)] (D) [(-1,3),(5,-2)]

Two consecutive vertices of a rectangle of area 10 units ^(2) are (1,3) and (-2,1). Other two vertices are ((-3)/(5),(21)/(6)),(-(18)/(5),(1)/(5))(b)(-(3)/(5),(21)/(5)),(-(2)/(5),(11)/(5))(-(2)/(5),(11)/(5)),quad ((13)/(5),(9)/(5)) (d) ((13)/(5),(9)/(5)),(-(18)/(5),(1)/(5))
