Question

1. Represent the following inequalities graphically by shading the unwanted region
   x≥0, y≥0, x+y≥5, x+y≤10, y≤7, x≤7 
2. write down the coordinates of one point that is inside the wanted region 
3. Name the figure formed by the unshaded region 
4. measure and find the sum of all the angles in the figure formed in (c) above. 

Answer 1

1.  x+y≥5

   x	0	5
   y	5	0

   x+y≤10

   x	0	10
   y	10	0

   
2. Any one
3. Hexagon
4. 135° × 4
   90° × 2
