Answer:
7√2 units
Step-by-step explanation:
The distance between two points having coordinates (x1, y1) and (x2, y2) is given by,

Here, x1=-4 and y1=2
 x2=3 and y2=-5




 
        
                    
             
        
        
        
Answer: c
Step-by-step explanation:
 
        
                    
             
        
        
        
Since the distance of MN is 31 and we have a distance of ML
of h -15 and LN of 2h – 8, therefore
ML + LN = h -15 + 2h – 8 = 31
 h = 18
substituting the value of h to the expression for LN
obtaining
 
LN = 2h – 8
LN = 2(18) – 8 
LN = 28
 
Therefore the length of the segment LN is 28 units
 
        
             
        
        
        
Answer:
Step-by-step explanation:
y + 1 = -9(x + 9)
y + 1 = -9x - 81
y = -9x - 82

Answer:
The number is 12
Step-by-step explanation:
Let x be the number
160/100 = 1.6
1.6 x = 19.2
x = 19.2 / 1.6
x = 12
