Answer:
<h2>The width is 13</h2>
Step-by-step explanation:
From the question
P=2L+2W
where
L is the length
W is the width
To make W the subject move 2L to the left side of the equation
That's
2W = P - 2L
Divide both sides of 2 to make W stand alone
We have
when
P = 70
L = 22
W is
We have the final answer as
<h3>W = 13</h3>

To correctly graph this, you need to set up a simple equation and table of values. Luckily, this equation is dead-simple; I'll define <em>y</em> as the total cost and <em>x</em> as the number of water bottles sold.
Since 1.50$ is the cost for one bottle, multiplying that with your variable that defined the amount of bottles, <em>x</em>, gets you the total, <em>y</em>. Now that we have a basic equation, we can begin plugging in values.
Recall that a function is basically just something that takes in a value and returns another one; in our case, it takes the <em>amount of bottles</em> and returns the <em>total cost. </em>Now, plug in the x-values present on the graph (specifically only whole numbers, since you can't have a half bottle). I can't make a proper table but I'll make do.
x y
--------
0 0
1 1.5
2 3
3 4.5
4 6
5 7.5
-----------
Great, now that you have a table of values all you have to do is plug them into the graph, which I've attached. It's pretty crude since I drew it in mspaint but I'm sure you get the point at this point.
The answer is 88 Bc 8 x 11 is 88
Here we can use the distance formula. We label one point
and the other
. It doesn’t matter which point we label with the 1s and which we label with the 2s. The distance will be the same either way (the distance from the subway to the house is the same as that from the house to the subway — to give a related easier to follow example). What does matter is that the 1s are together and the 2s are together.
So let’s call (-4,-3)
which means that -4 is
and -3 is
. We call the other point (4,3)
The distance formula is
We substitute using the points given and obtain:
and simplify to get
The distance is 5 miles
