Answer:
54
Step-by-step explanation:
64 + 62 = 126
180 - 126 = 54
 
        
                    
             
        
        
        
C
20% increase
$50 + 20% = $60
        
                    
             
        
        
        
Solve each equation with (0, 3)
y = -x + 3
3 = -0 + 3
y = 3 (correct since y = 3 in (0, 3))
y = 2x - 3
3 = 2(0) - 3
3 = 0 - 3
3 = -3 (incorrect since it isn't equal)
So... No, because it does not check in the second equation.
Best of Luck!
 
        
             
        
        
        
Step-by-step explanation:
Let the coordinates of point b be (x,y).
Given the coordinates of a (-7,5) and c(5,-1)
Now according to question
ab = 5bc
using distance formula 
 
 
Solving we can get 
 '
'
However, we do need either x or y coordinate of point b to find the other.
