Since we are asked to find the rate of change from Monday to Wednesday, we are dividing by 2, since Monday is day 1 and Wednesday is day 3. 3 - 1 = 2.
1800 + 500 = 2300 calories consumed Tuesday.
2300 - 100 = 2200 calories Wednesday.
(2200 - 1800)/2 = 400/2 = 200 calories

so all you do is combined together and got -6.4n + 9.8 
 
        
                    
             
        
        
        
Answer:
<u>(2) x </u> <u> 4</u>
<u> 4</u>
Step-by-step explanation:
Given the sqrt(x),  x  zero
 zero
So, given sqrt(x -4),  x -4  0
 0
Now solve for x
x - 4  0
 0
x  4
 4
