Answer:

The answer is y= -4x-14

y= 1/4x - 7 (-2, -6)

y=1/4x - 7

suppose the number of fiction books is 2/7 times the number of nonfiction books. what would be the ratio of the numbers of nonfi
Elis [28]
Well, the total amount of books is all fiction books and nonfiction books, let's say is "x", total

now, the fiction books are 2:7 or 2/7 to nonfiction

so, if we divide the total "x" by 2+7, or 9, 2 of those quotients go to fiction and 7 of those go to nonfiction

if we divide "x" by 9, a "whole" is 9/9 or (9/9)x or 1x or just "x"

and we know 7 of those 9ths belong to nonfiction, thus

\bf \begin{array}{clclclll}
\cfrac{2}{9}&+&\cfrac{7}{9}&=&\cfrac{9}{9}\\
\uparrow &&\uparrow &&\uparrow \\
fiction&&nonfiction&&whole
\end{array}\\\\
-----------------------------\\\\
\cfrac{nonfiction}{whole}\implies \cfrac{7}{9}\implies 7:9\impliedby ratio

Alika [10]

Answer:

a. .15 b. 5.40

Step-by-step explanation:

Hi! The first thing you want to do is find the unit rate, which would be 9 divided by 60. This should be 15 cents per hour. Next, for the second part, you multiply by 36, which should be $5.40. Hope this helps!

How about "miles per hour?"  I drive "45 miles per hour" on my way into town.
That's a unit rate.

Did you know that 2 pints = 1 quart?  You could write this rate / ratio as

2 pints
---------
 1 qt

or as

 (1/2 qt)
-----------   this is a measure of one quantity per unit of another quantity.
  1 pint
