Answer:

y = 6x + 90
210 kg

Step-by-step explanation:

This is a linear relationship:

y = mx + b

We have:

m = 6 and a point (8, 138)

Work out the y-intercept by using the above information:

138 = 6*8 + b
b = 138 - 48
b = 90

The equation is:

y = 6x + 90

Find the value of y when x = 20:

y = 6*20 + 90 = 120 + 90 = 210 kg

Answer:

The weight after 20 months is 210 kilos.

Step-by-step explanation:

1 month = 6 kilos
=> 8 months = 6 x 8 = 48 kilos
=> x + 48 = 138
=> x = 90

This means that the starting point is 90 kilos.

=> 1 month = 6 kilos
=> 20 months = 6 x 20 kilos
=> 20 months = 120 kilos
=> 90 + 120 = weight in 20 months
=> 210 kilos = weight in 20 months

Hence, the weight after 20 months is 210 kilos.
