Answer:

Relation

Explanation:

The definition of a relation is just a set of ordered pairs.

A function is a relation in which each domain element is paired with exactly one range element.  

It can't be a function because if it is a vertical line, then the x-value is the same for the whole line.

I hope that helps a bit

County sales tax = 103,500 x 2.9% = 3,001.50
City sales tax      = 103,500 x 1.9%  =<u>1,966.50</u>

A certain drug is made from only two ingredients: compound A and compound B. There are 3 milliliters of compound A used for ever
Sphinxa [80]

Answer:

304\dfrac{4}{7}\ milliliters

Step-by-step explanation:

If there are 3 milliliters of compound A used for every 4 milliliters of compound B, then we can denote that we use 3x milliliters of compound A and 4x milliliters of compound B to get 533 milliliters of the drug. Thus,

3x+4x=533,\\ \\7x=533,\\ \\x=\dfrac{533}{7}\ milliliters.

Hence, a chemist must take

4\cdot \dfrac{533}{7}=\dfrac{2132}{7}=304\dfrac{4}{7}\ milliliters

of compound B.
