Answer» CORRESPONDING equation : ` 3x + 2y = 150 ` This LINE passes through the points A(50, 0)and B((0, 75). AB. At point (0, 0), from the inequation, `0le 150` (True) `:.` The solution of this inequation is that region of XY- plane in which (0, 0) lies. This line passes thrugh the point C(80, 0) and D(0, 20). Join CD. At point (0, 0), from the inequation, `0 le 10(True)` `:.` The solution of this inequation is that region of XY-plane divided by line CD in which (0, 0) lies. The solution of ` x ge 0, y ge 0 is in first quadrant. The solution of x`ge` 15 is x = 15 and its left SIDE  `:.` The common solution of given inequations is shown by the shaded region. |
