Answer:
we plot first the data and find the equation. The equation is c(x) = 7x2 - 3x + 5. when x is equal to 5, then c(x) is equal to $165
Step-by-step explanation:
Y=1x-10 (sorry I could be wrong)
The answer is 20 y=9 times that and y= 9 times that also u subtract and then u get 20.
Answer:
Step-by-step explanation: The earth rotates 34 km every 32 seconds. We can simplify this by dividing both sides by 32. Now, we have 34/32 km every 32 seconds. Now, to further simplify this, we need to convert 34/32 to a mixed number 34/32 = 1 2/32 which then can be simplified to 1 1/16. So, near the equator, the speed of Earth's rotation is 1 1/16 km per second.
Solution:
As one of the fraction is a proper fraction and another one is Mixed fraction.
There are two methods of solving it.

2. ![\frac{1}{2}\times-4 \frac{4}{5}=\frac{1}{2}[-4-\frac{4}{5}]=\frac{1}{2}\times (-4)+\frac{1}{2}\times\frac{-4}{5}=-2+\frac{-2}{5}=\frac{-10-2}{5}=\frac{-12}{5}=-2\frac{2}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%5Ctimes-4%20%5Cfrac%7B4%7D%7B5%7D%3D%5Cfrac%7B1%7D%7B2%7D%5B-4-%5Cfrac%7B4%7D%7B5%7D%5D%3D%5Cfrac%7B1%7D%7B2%7D%5Ctimes%20%28-4%29%2B%5Cfrac%7B1%7D%7B2%7D%5Ctimes%5Cfrac%7B-4%7D%7B5%7D%3D-2%2B%5Cfrac%7B-2%7D%7B5%7D%3D%5Cfrac%7B-10-2%7D%7B5%7D%3D%5Cfrac%7B-12%7D%7B5%7D%3D-2%5Cfrac%7B2%7D%7B5%7D)
→→Here i have used Distributive property with respect to addition and Subtraction i.e a×(b+c)= a ×b + a×c or a×(b-c)=a×b-a×c
