Answer:
hi there! i can help you out! i don't want you to get a zero on your report card!! 
Step-by-step explanation:
so, on the x-axis, which is all the numbers through 1-10 and there are the patient's number. so for ex, the first question says patient 1 : 3 hours right??
so the hours are the y-axis and you can label them 2,4,6,8 because skip counting by twos are probably the easiest! so for the first question, you would line a dot up on top of 1 and go up and you see 2 and 4 right, cuz you just labeled it... do go between 2 and 4 which is 3 and place the dot there...
and keep doing the same things with other ones too...
another ex! so on the second question, it says patient 2 : 7 hours so place the dot on top of the 2 and go up untill you see 6 and 8 and place the dot beween them!
 
 
        
                    
             
        
        
        
Option C: -3 is the average rate of change between  and
 and 
Explanation:
The formula to determine the average rate of change is given by
Average rate of change = 
We need to find the average rate of change between  and
  and 
Thus, from the table, we have,
 ,
 , 
 ,
 , 
Thus, substituting these values in the formula, we get,
Average rate of change = 
                                         
                                         
Thus, the average rate of change between  and
 and  is -3.
 is -3.
Hence, Option C is the correct answer.
 
        
             
        
        
        
X=34.78 y= 238.8..............
        
             
        
        
        
The answer should be C because that’s the most reasonable and because you can’t simplify 125/7
        
                    
             
        
        
        
Set up the following equations:


110 represents the lengths of the length and width of the triangle, as you'll divide total perimeter of the rectangle, 220, by 2 to find the individual lengths. 20 is the difference between the length and width.
We'll use elimination for this system of equations, as there are opposite coefficients for W in both equations. Combine the two equations:

Divide both sides by 2 to get L by itself:
 The length of the rectangle is 65 feet.
The length of the rectangle is 65 feet.Plug this value into the second equation:

Add W to both sides:

Subtract 20 from both sides:
 The width of the rectangle is 45 feet.
The width of the rectangle is 45 feet.
