Answer (4):
a=ub/k because
u=ak/b   (starting equation)
ub=ak    (multiply b to both sides)
a=ub/k   (divide both sides by k)
Answer (6)
x=g+c-y because
g=x-c+y  (starting equation)
x+y=g+c (add c to both sides)
x=g+c-y  (subtract y from both sides)
 
        
             
        
        
        
You already have figured the main idea. In this case, the population is growing 1.9% a year. This word can be translated into: multiplied by 101.9% (100+1.9%). That means the P0 is 6 bill, the base is 101.9%(or 1.019) and the time is 50 years. The calculation would be:
<span>P(t)=P₀a^t
</span>P(t)=6 billion * 101.9%^50= 6 billion * <span>2.56276= 15.38 billion</span><span>
</span>
        
             
        
        
        
It can't be factored because there are no 2 numbers that when you multiply you get 35 and when you add you get 13.
        
             
        
        
        
Answer:
i dont know
Step-by-step explanation:
 
        
             
        
        
        
 
(f+g) (n) = (–5n +1 ) + (- 6n +2) = –11n +3
(f+g) (n) = –11n +3
(f+g) (–2) = – 11 (–2) +3 = 22 +3 = 25
I hope I helped you^_^
