Suppose that and be two points and P be a point on x- axis such that is minimum then the point P is
detailed solution
Correct option is D
Suppose that the images of A5,6 and B3,4 in the X- axis are C and D respectively. The point P is the point of intersection of the lines AD and x- axis, it is coincide with the point of intersection of the lines BC and x- axisThe image of B3,4 in the x- axis is D3,−4The equation of the line joining D3,−4 an A5,6 is y−6=6+45−3x−5This can be simplified as y−6=6+45−3x−5y−6=5x−5y−6=5x−255x−y−19=0Plug in x=0 to get the point of intersection of the above line and axis. It implies that5x=19x=195Therefore, P=195,0Talk to our academic expert!
