Answer:
5.4 inches
Step-by-step explanation:
This is all about ratios proportions and similarity.
First the 8.5 stays the same you scale only the 11 down to 7
because it says to scale length down to 7
so once you scale it down you should get 5.4 inches for the width once you plug it back in
Answer:
The answer is
<h2>
![y = - 3x - 11](https://tex.z-dn.net/?f=y%20%3D%20%20-%203x%20-%20%2011)
</h2>
Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
From the question
<h3>
![y = \frac{1}{3} x + 4](https://tex.z-dn.net/?f=y%20%3D%20%20%5Cfrac%7B1%7D%7B3%7D%20x%20%2B%204)
</h3>
Comparing it with the general equation above
Slope / m = 1/3
Since the lines are perpendicular to each other the slope of the other line is the negative inverse of the original line
That's
Slope of perpendicular line = - 3
Equation of the line using point (-4 , 1) and slope - 3 is
<h3>
![y - 1 = - 3(x + 4) \\ y - 1 = - 3x - 12 \\ y = - 3x - 12 + 1](https://tex.z-dn.net/?f=y%20-%201%20%3D%20%20-%203%28x%20%2B%204%29%20%5C%5C%20y%20-%201%20%3D%20%20-%203x%20-%2012%20%5C%5C%20y%20%3D%20%20-%203x%20-%2012%20%2B%201)
</h3>
We have the final answer as
<h3>y = - 3x - 11</h3>

Hi there! $8 per 4 bottles means price/# of bottles will give you the average price per bottle.
8/4=$2
Therefore it is $2 for 1 bottle.
Hope this helps!
