We know the amount of water is 1 liter and the milk is 20% of that. Let y be the total amount of liquid in the bottle.
so
y=1+(0.2*1)

I think the correct answer is
D.
the product of x and a factor depending on x
SORRY if I am wrong.
Answer:
y = -1/6x + 5
Step-by-step explanation:
y = mx + c
Gradient (m) = -1/6
Y-intercept (c) = 5
so
y = -1/6x + 5
Answer:
x = 3
Step-by-step explanation:
x = 4 - 5x + 14
x = 18 - 5x
x + 5x = 18
6x = 18
x = 3
