, then
9 ![\frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D)
= ![\frac{9(3)+1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B9%283%29%2B1%7D%7B3%7D)
= ![\frac{27+1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B27%2B1%7D%7B3%7D)
= ![\frac{28}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B28%7D%7B3%7D)
Have you tried doing 6 in x 4 in, if not try that
Let's get this equation into a usable format, which is
<em>y=mx+b</em><em /> (where m is the slope and b is the y-intercept), before graphing.
First, we move our x terms onto one side, so that the y terms are on one side, and the x terms on another side. Keep in mind that this will negate (multiply by -1) the x term we move.
<em>2y = -5x - 10</em>
Then we isolate y. We'll do this by dividing by 2.
<em>2y/2 = -5/2x - 10/2</em>
y = -5/2x - 5We now have the equation in y=mx+b format. We can now graph (it should look something like the one below).
Slope: -5/2
Y-Intercept: -5:)
Answer:
<h2>
$172</h2>
Step-by-step explanation:
Given that the revenue for x items is 3x
75% of the revenue
![=\frac{75}{100} *3x\\\\= 0.73*3x\\\\=2.25x](https://tex.z-dn.net/?f=%3D%5Cfrac%7B75%7D%7B100%7D%20%2A3x%5C%5C%5C%5C%3D%200.73%2A3x%5C%5C%5C%5C%3D2.25x)
The equation for the profit is given as
g= 2.25x-35
Given that x= 92, the profit will be
g= 2.25(92)-35
g= 207-35
g= 172
