Answer 1

Answer:

If 4x + 6y = 3xy and 8x + 9y = 5xy then

x = 2, y = 3

x = 1 , y = 2

x = 3 , y = 4

x = 1 , y = -1The graph of the equations 5x - 15y = 8 and 3x -9y = 24/5 are two lines which are

Coincident

Parallel

Intersecting exactly at one point

Perpendicular to each otherThe graphs of the equations 6x - 2y + 9 = 0 and 3x - y +12 = 0 are two lines which are
