B.
The cost for x children and y adults to go to the movies if adult tickets are $11 and child tickets are $6.
Example 3 children and 2 adults ( 6(3) + 11(2) )
        
                    
             
        
        
        
|x-10| when x = -8
| - 8 - 10 | = |-18| = 18 <==
        
             
        
        
        
X = low-energy lamp
y = high-energy lamp
1) 4x + 5y
2) 120= 4x + 5y
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
The point-slope form of an equation of a line:

m - slope
Parallel lines have the same slope.
We have the equation in the slope-intercept form (y = mx + b)

Put to the point-slope equation value of the slope and the coordinates of the point (4, -5):

 
        
             
        
        
        
16x² - 8x + 1 = (4x)² - 2 · 4x · 1 + 1² =(4x - 1)²
Used: (a - b)² = a² -2ab + b²
