Answer: 10n^2 - 10
Step-by-step explanation:
(5n - 5)(2+2n) becomes (5n-5)(2n+2)
= (5n)(2n) + (5n)(2) + (-5)(2n) + (-5)(2)
= 10n^2 - 10

Answer:
   the correct choice is marked
Step-by-step explanation:
The line has a rise of 2 for a run of 1, so a slope of 2. The line crosses the y-axis at y=-2, so the y-intercept is -2. The slope-intercept equation for the line is ...
   y = mx + b . . . . . . for slope m and y-intercept b
   y = 2x -2
 
        
                    
             
        
        
        
The first thing you should do in that case is to graph both lines.
 Once graphed you must see which region of the Cartesian plane they meet their respective inequalities.
 The solution of the inequation system is the shaded region shown.
 The point sought is
 P = (5, -2)
