Step-by-step explanation:
Answer:
10rupee notes are 11
20rupee notes are 22
Step-by-step explanation:
Let 10-rupee note be x
20-rupee note will be x + 11
The equation will be
10x + 20(x + 11) = 550
10x + 20x + 220 = 550
30x = 330
x = 330/30 = 11 = 10rupee notes
y = 11+11 = 22 = 20rupee notes
Y=4-x
0= -x^2 + 3x
x=0 or 3
so y = 4-0 or y= 4-3
y=4 or 1
The two points are:
(0,4) and (3,1)
