Answer is A
        
             
        
        
        
Answer:
9440
Step-by-step explanation:
4% of 9000=360. Knowing that, we can do 9000-360 which equals 8640+800 is 9440. Hope this helps :)
 
        
             
        
        
        
Answer:
b=4
Step-by-step explanation:
-14+2b= -2b+2
Add 2b to each side
-14+2b+2b= -2b+2b+2
-14+4b =2
Add 14 to each side
-14+4b+14= 14+2
4b = 16
Divide each side by 4
4b/4 = 16/4
b =4
 
        
                    
             
        
        
        
Answer:
-8 ≤ x ≤ - 6
 2 ≤ x ≤  6
Step-by-step explanation:
Increasing part of the function can be easily determined from the graph.
Note that increasing function means for each successive values of 'x', the values of 'y' keep increasing. 
From the graph, we see that the function is increasing in the interval 
Between -6 and -4, the graph is constant and takes the value 4.
After that it decreases till x = -2 until it becomes a constant function again on x = 2.
Then, it again increases from x = 2 till x = 6. This is represented by the interval
 .
.
Then it again decreases.
So, OPTION A and C are the answers.
