If the ratio of x/y or x/y is always the same constant, then a and y are directly proportional and the constant is called the constant of proportionality.
<span>If the product of xy is always the same constant, then a and y are inversely proportional and the constant is called the constant of proportionality. </span>
<span>unit rates --- are like any rate found by dividing --- like speed --- miles per hour unit means 1 and this is miles traveled in one hour (at constant speed) --- so you just divide --- traveling 100 miles in 2 hours = 50 miles in 1 hour --- 50 miles per hour --- miles/hour <<< that is a unit rate </span>
<span>slope is a rate of change --- on an x-y coordinate axis graph the slope is the rate of change of y compared to a change in x --- this is not necessarily a unit rate ... slope of 2/3 means a change of 2 for y will create a change of 3 for x (not a change of 1, so it is not a unit rate)</span>
Here are the basic steps on how to do it.
<em>4-7x=18</em>
Now you move the 4 onto the other side of the equal bars.
<em>4-4-7x=18-4</em>
Do the total.
<em>-7x=14</em>
Now you divide 14 by -7.
<em>x=-2</em>
There you have it.

Answer:
The volume punch made of 158.90 ounces.
Step-by-step explanation:
Given that the ratio of fruit juice to the sparking water in a punch recipe:
![\frac{Juice}{Water}=\frac{24}{33}](https://tex.z-dn.net/?f=%5Cfrac%7BJuice%7D%7BWater%7D%3D%5Cfrac%7B24%7D%7B33%7D)
Volume of sparking water = 92 ounces
Volume of Juice required be V
![\frac{V}{92 ounces}=\frac{24}{33}=66.90 ounces](https://tex.z-dn.net/?f=%5Cfrac%7BV%7D%7B92%20ounces%7D%3D%5Cfrac%7B24%7D%7B33%7D%3D66.90%20ounces)
Volume of the punch; 92 ounces + 66.90 ounces = 158.9 ounces
The volume punch made of 158.90 ounces.
9 + 10h + -5h=0
19 + -5 =0
14=0
