When you have a negative exponent, you move it to the other side of the fraction to make the exponent positive.
For example:
or ![\frac{x^{-2}}{1}=\frac{1}{x^2}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B-2%7D%7D%7B1%7D%3D%5Cfrac%7B1%7D%7Bx%5E2%7D)
or y²
So:
![5^{-2}=\frac{1}{5^2}=\frac{1}{25}](https://tex.z-dn.net/?f=5%5E%7B-2%7D%3D%5Cfrac%7B1%7D%7B5%5E2%7D%3D%5Cfrac%7B1%7D%7B25%7D)
Your answer is B
Answer:
Step-by-step explanation:
7*3x= 7- 3x - 9
21x = -2-3x
24x =-2
x=-1/12
The median would be: 7.9
and the mean would be:7.4714285714 (you are able to chop that down a bit if needed)
1060.5263157 etc your teacher prob tells you to round
Answer:
Step-by-step explanation:
<u>Use the area equation:</u>
<u>Substitute values:</u>
- A = 1/2* 1 2/3 * 1 = 1/2*5/3 = 5/6 km²
