Answer:
$57.60
Step-by-step explanation:
20% turns into a decimal .20
72*.20 =14.40
72.00-14.40 = $57.60
C is equal to -28 because if you do it backwards, you will get -28.
Answer:
![(\frac{g}{f} )(x)=\frac{x^2-6}{3x+1}](https://tex.z-dn.net/?f=%28%5Cfrac%7Bg%7D%7Bf%7D%20%29%28x%29%3D%5Cfrac%7Bx%5E2-6%7D%7B3x%2B1%7D)
Step-by-step explanation:
f(x) = 3x+1
g(x)= x^2- 6
![(\frac{g}{f} )(x)= \frac{g(x)}{f(x)}](https://tex.z-dn.net/?f=%28%5Cfrac%7Bg%7D%7Bf%7D%20%29%28x%29%3D%20%5Cfrac%7Bg%28x%29%7D%7Bf%28x%29%7D)
Now we plug in g(x) and f(x)
we are given with g(x) and f(x)
![(\frac{g}{f} )(x)= \frac{g(x)}{f(x)}=\frac{x^2-6}{3x+1}](https://tex.z-dn.net/?f=%28%5Cfrac%7Bg%7D%7Bf%7D%20%29%28x%29%3D%20%5Cfrac%7Bg%28x%29%7D%7Bf%28x%29%7D%3D%5Cfrac%7Bx%5E2-6%7D%7B3x%2B1%7D)
We cannot factor and simplify it
![(\frac{g}{f} )(x)=\frac{x^2-6}{3x+1}](https://tex.z-dn.net/?f=%28%5Cfrac%7Bg%7D%7Bf%7D%20%29%28x%29%3D%5Cfrac%7Bx%5E2-6%7D%7B3x%2B1%7D)
Answer:
Your answer is:
10 over 40 plus 9 over 39 or C
This is because there are 40 boxes in total. The chance of a white box being handed out is 10/40. If a white box is handed out as a prize, there are going to be 39 boxes left, but only 9 of those 39 boxes would be white.
Ideally, tree diagrams should be used to solve such problems.
