A, B and C working together will finish same piece of work in 10 days
A can do a piece of work in 20 days. That is A is doing the work at a rate of 1 / 20. Therefore
B = 1 / 30
C = 1 / 60
A, B and C working togehter their rate will be added together =
A + B + C = 1 / 20 + 1 / 30 + 1 / 60 = 1 / 10
so they can work together to finish same piece of work in 10 days
Y = 10x + 4
x y
-2 10(-2)+4 = -16
-1 10(-1)+4 = -6
0 10(0)+4 = 4
1 10(1)+4 = 14
2 10(2)+4 = 24
