ANSWER

EXPLANATION
The given line passes through the origin, hence it has equation of the form,

Therefore y varies directly as x.
The line passes through the point (3,1)
This implies that,


Hence the constant of variation is

The equation is

Answer:
The angles remain the same for all values of n. After a dilation, the angle measurements for the image and the preimage are always equal.
Step-by-step explanation:
The equation that best models this situation would be: y=40+30x
The dependent variable depends on the independent do depending on how many bags you buy, the price changes so for 5 bags the price is $15 and for 10 bags the price is $30
The value of f(x) is 18 because when there is 1/2, think about half (i think like that). so what is the half of 36? 18.
