Answer: OPTION B
Step-by-step explanation:
The equation of a line that passes through the origin is the following:

Where "m" is the slope of the line.
By definition, Proportional relationships have the following form:

Where "k" is the Constant of proportionality.
Then, as you can notice, if you graph a Proportional relationship you will get a line that passes through the origin.
Therefore, based on the explained above, you can conclude that the option that shows a function that represents a Proportional relationship is the Option B.
Then, this is:

The simple radical form of 5 and 45 is 9
False. Although, I'm not 100% sure.
In each quantity of 87 cg, 1 of them is active ingredient. In the quantity of interest,
... (1/87)·522 cg = 6 cg . . . is active ingredient
The remainder of that quantity, 516 cg, is inactive ingredient.
