Answer:
(a) (i) x + y ≤ 24
(ii) y ≥ 4 + x
(b) draw a graph with the coordinate given below:
* note that you must draw 2 lines in your graph as there are 2 linear inequalities
(i) (0,24) and (24,0)
(ii) (0,4) and (-4,0)
*when the sign is ≤ , shade below the drawen line on the graph.
*when the sign is ≥, shade above the drawen line on the graph.
(c) x=8
8 + y ≤ 24
y ≤ 16 ( maximum )
y ≥ 4+8
y ≥ 12 (minimum)
