Answer:
c. -oo < x < -1
Step-by-step explanation:
according to the graph the function possitive
 => y > 0 , and x < -1
 
        
             
        
        
        
Answer:

This function has vertex at origin
Let's verify
Put (0,0)
Hence verified
 
        
                    
             
        
        
        
The answer is 14. This is because 63=3+x+3x-4. Then You just subtract it and then you get 64=4x. Then you just divide it and then you get x=16.
 
        
             
        
        
        
If 80% are women, then 20% are men
20% of what equals 880
0.20x = 880
x = 880/.20
x = 4400
check..
men : 20% of 4400 = 0.20(400) = 880
women : 80% of 4400 = 0.80(4400) = 3520
totaling : 3520 + 880 = 4400
so there are a total of 4400 workers
