P = 2(3x) + 2x
I'm not sure, just like a toddler spellchecking your second sentence.
Unit rate is a rate that has a denominator of 1. In order to get the unit rate given the denominator is not 1, then unit rate is acquired by getting the equal ration with denominator 1. On the question, Letter A. 4 yd/carry, Letter B. 35 mi/1gal and Letter D. 3 cups per batch are unit rates.
so it'd be the first, third and fourth one. all you gotta do is draw a vertical line through the middle of the 1st, 3rd and 4th.
Answer:
a) 
b) 394 thousand = 394,000 people will be following the website in 2016
Step-by-step explanation:
Exponential equation for an amount:
The exponential equation for an amount after t years has the following format:

In which y(0) is the initial value and r is the growth rate, as a decimal.
A social media website had 350,000 followers in 2010. The number y of followers increases by 2% each year.
This means that: 
a. Write an exponential growth function that represents the number of followers t years after 2010
In thousands:


b. How many people will be following the website in 2016?
2016 is 6 years after 2010, so this is y(6).

Rounding to the nearest thousand:
394 thousand = 394,000 people will be following the website in 2016
