Answer:1) c. 5,9,13,17,21
2)  a. a1=8, an=an-1 -2
Step-by-step explanation: 1) an=4n+1
     ⇒ a1=4×1+1=5
          a2=4×2+1=9
           a3=4×3+1=13
           a4=4×4+1=17
            a5=4×5+1=21
2) clearly a1=8 and then the terms of series are decreasing by 2
 so, an=an-1 -2
 
        
                    
             
        
        
        
Annual interest
50000 * (9.5 / 100)
4750
Interest for 12 months = 4750
Interest for 8 months 
(4750/12) * 8
$ 3166.67
        
             
        
        
        
Answer:
Y=7x+9
Step-by-step explanation:
Y=mx + b
b= y-intercept
m=slope
Substitute:
Y=7x+9
 
        
             
        
        
        
The answer is C.) x = 7; x = -6 
 
        
                    
             
        
        
        
Answer:
All you have to do is find the rest of the percentage. Percentage adds up to 100%. So you will have to add the two percentages they gave you. 27+33=60%. Now you have to take away 60 from 100. 100-60=40%.
40%- That's the answer.
Hope this helps.
