Answer:
Step-by-step explanation:
 x(x-2y)-(y-x)2  
Final result :
  -y2
Step by step solution :
Step  1  :
Equation at the end of step  1  :
  x • (x - 2y) -  (y - x)2
Step  2  :
 2.1     Evaluate :  (y-x)2   =    y2-2xy+x2  
Final result :
  -y2

Plotting the data to get the line of best fit, it is:
y<span> = 0.087</span>x<span> + 0.587
substitute x=2030-1980=50,
y = $4.94 is the price in 2030</span>
        
             
        
        
        
B is the correct answer because it shows the solution set of an inequality
