If one value is inversely proportional to another then it is written using the proportionality symbol in a different way. Inverse proportion occurs when one value increases and the other decreases. For example, more workers on a job would reduce the time to complete the task. They are inversely proportional.
Answer:
Step-by-step explanation:
Given: ![7-3[(n^{3} +8n)\div (-n)+9n^{2} ]](https://tex.z-dn.net/?f=7-3%5B%28n%5E%7B3%7D%20%2B8n%29%5Cdiv%20%28-n%29%2B9n%5E%7B2%7D%20%5D)
Now simplifying expression using PEDMAS
First solving for small parenthesis.
taking common of n
= ![7-3[n(n^{2} +8)\div (-n)+9n^{2} ]](https://tex.z-dn.net/?f=7-3%5Bn%28n%5E%7B2%7D%20%2B8%29%5Cdiv%20%28-n%29%2B9n%5E%7B2%7D%20%5D)
using law of indices, 
= ![7-3[-(n^{2} +8)+9n^{2} ]](https://tex.z-dn.net/?f=7-3%5B-%28n%5E%7B2%7D%20%2B8%29%2B9n%5E%7B2%7D%20%5D)
Opening parenthesis
= ![7-3[-n^{2} -8+9n^{2} ]](https://tex.z-dn.net/?f=7-3%5B-n%5E%7B2%7D%20-8%2B9n%5E%7B2%7D%20%5D)
= ![7-3[ -8+8n^{2} ]](https://tex.z-dn.net/?f=7-3%5B%20-8%2B8n%5E%7B2%7D%20%5D)
Again using distributive property of multiplication
= 
=
Hence, the answer is
Answer:
5=b
y=-2x+5
Step-by-step explanation:
i aint never seen two pretty best friends its always one of em gotta be ugly
Answer:
1
Step-by-step explanation:
a= 2
b= 1, because there is no number before the x therefore it is a 1
c= -12, when you move the 12 from the right side over to the left, it becomes negative
first you start with 0 then you know that is yours nothing so you can cancel zero and then you can take the eight can round up so you take the 8 and put it one more to do so it's $4 so in total will be $4 that's the answer
