It is A, because a direct proportion follows the rule y=kx, and in A, k = 12 and it works for all of the x and y values
        
                    
             
        
        
        
Answer:
add 21 to both sides to get everything on one side 
x^2 - 10x + 21 = 0
do factorization, guess and check 
(x - 7) (x -3) = 0
x =7, and x =3
 
        
                    
             
        
        
        
Answer:
25%
Step-by-step explanation:
To solve this, we can use the percent change formula shown in the picture attached below.  is the new value,
 is the new value,  is the old value, and
 is the old value, and  represents the change. For this problem, 80 is the new value and 64 is the old value. Let's plug those numbers into the formula and solve for the percent change:
