The three terms are not like terms, so they cannot be added together.
The expression is simplified.
If you need to factor the expression, then the instructions should be factor the expression, not simplify.
        
             
        
        
        
Answer:
neither positive nor negative 
Step-by-step explanation:
In order to identify a type of correlation the points have to form where we can draw a line through the points and most of the points will be near that line drawn.
Because most of the points graphed are scattered we cannot identify if it has a positive or negative correlation

Answer: The population will be 408,000 people. 
Step-by-step explanation:
So in 2000 there were 200,000 people and it started to grow 8% every year so up to 2013. 
so find 8% of 200,000 and then multiply it by the  the number of years. 
8% * 200,000 =  16,000
Find the difference between the years. 
2013 - 2000 = 13 years 
13 * 16000 = 208000  This is the amount of new people from 2000 to 2013 so add it to the original population. 
208,000 + 200,000 = 408,000  
 
        
             
        
        
        
77.5%
Change to decimal:-
77.5 ÷ 100 = 0.775
775/1000
31/40
77.5% = 31/40
