Answer:


Step-by-step explanation:
step 1
Find the equation of the solid line
From the graph take the points (0,3) and (4,11)
Find the slope

The equation of the solid line in slope intercept form is equal to

we have

 ----> the y-intercept is the point (0,3)
 ----> the y-intercept is the point (0,3)
substitute

therefore
The inequality is 

step 2
Find the equation of the dashed line
The slope is given

From the graph take the y-intercept (0,-5) 
The equation of the solid line in slope intercept form is equal to
 
     
we have

 
 
substitute

therefore
The inequality is 

because the shaded region is below the dashed line
therefore
The system of inequalities is 


 
        
             
        
        
        
Answer:
he used 1,571
Step-by-step explanation:
if you divide 4,713 by 3, you get 1,571 and that amount is equal to just 1/3 of the amount.
 
        
             
        
        
        
You can use your calculator if you have one or do long division. just make sure to move the decimal so it looks like this: 63 divided by 7. you answer should be 9
        
                    
             
        
        
        
out of these, it would be 4x - 4 * 2
