Answer:
Step-by-step explanation:
The answer is c.
Proportional means a relationship of y = a constant multiplied by x
In this case, the constant is 7.
i.e. y = 7x
So if
x is 3, y is 21
x is 5, y is 35
x is 7, y is 49
and so on...
And there you have it.
 
        
             
        
        
        
Answer:
C
Step-by-step explanation:
From the given coordinates
A(6, 0), B(0, 0) then AB = 6 - 0 = 6
B(0, 0), C(0, 8) then BC = 8 - 0 = 8
To calculate AC use Pythagoras' theorem on the right triangle formed
AC² = AB² + BC² = 6² + 8² = 36 + 64 = 100
Take the square root of both sides, hence
AC =  = 10
 = 10
Perimeter = AB + BC + AC = 6 + 8 + 10 = 24 → C
 
        
             
        
        
        
Answer:
 -8
Step-by-step explanation:
m= y₂- y₁/ x₂-x₁
m= 1-9/7-6
m= -8/1 
m= -8
 
        
                    
             
        
        
        
Your answer would be 18. AC must be longer than 9
