3.5x-10>-3  add 10 to both sides
3.5x>13  divide both sides by 3.5
x>26/7
x=(26/7, +oo)
...
8x-9<39  add 9 to both sides
8x<48  divide both sides by 8
x<6
x=(-oo,6)
Since this is a compound inequality with AND the solution set will be the union of the two intervals found above.
x=(26/7, 6)
        
                    
             
        
        
        
Answer:
No it is not a factor
Step-by-step explanation:
Reason for not being a factor is 3x^3-4x^2-4x. 3x3−4x2−4x 3 x 3 - 4 x 2 - 4 x. Factor x x out of 3x3−4x2−4x 3 x 3 - 4 x 2 - 4 x
 
        
             
        
        
        
Sum of the terms of the series is
Sn = n/2 ( a1+an )
we have n= 6 , a1= 17, an = 57 
so Sn = 6/2 ( 17+57) = 3(74) = 222
        
             
        
        
        
Answer:
30.5 is the answer
Step-by-step explanation:
price of 1 bagels=0.85
price of 1 cream cheese=2.5
30*0.85+2*2.5
25.5 +5
30.5 
just multiply  with the number of thing by the price of  1 thing
 
        
                    
             
        
        
        
Solution :
Let A = Economics, B = Mathematics
n(A) = 311, n(B) = 243, 
a). So, 
                      = 311 + 243 - 135
                      = 419
b). n(A only) = 311 - 135
                    = 176
      n(B only) = 243 - 135
                    = 108
Exactly one of these two courses 
   
   = 0.568
c). Neither economics nor mathematics
     
   
  = 0.162
