answer:
15
step-by-step explanation:
9, 10, 15, 17, 15, 14, 37, 45, 42, 13
- mode means the number that appears the most
- in the set of numbers, 15 appears twice, which the others appears only once
 
        
                    
             
        
        
        
4 : 8
x 9 => 36 : 72  <=== equivalent
 
        
                    
             
        
        
        
Well, first off, let's find what is the slope of BC

now, a line perpendicular to that one, will have a negative reciprocal slope, thus

now, we know the slope "m" of AB is -2 then, thus

Answer:    1.) x - 2y = 4 , add 2y to both sides. ---> answer is, X = 2y + 4
2.) 2x - 6y = 8, Add 6y to both sides, then divide both sides by 2. --> answer is, X = 3y + 4
