Since y must equal both 3x+2 and x-4, we deduce that 3x+2 and x-4 must equal each other. So, we have

 
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
y - 9 = 3(x - 0)
y - 9 = 3x - 0
y = 3x + 9
 
        
             
        
        
        
Answer:

Step-by-step explanation:
Since, according to associative property of multiplication,
a(bc) = (ab)c,
Where a, b and c are any real numbers,
Here, the given expression,
2 × ( 5 × 1.5 ),
By applying the associative property of multiplication,
( 2 × 5 ) × 1.5,
Hence, the appropriate expression in the first box is '(2×5)'
And, the appropriate number in the second box is '1.5'.

Answer:
D. The sum is a rational expression.
Step-by-step explanation:
the given expression is  a/b +c/d
so in the question it is given that b and d are non zero values 
 a/b is rational number and c/d is a rational number 
 so if both are rational number , so we know that the sum of rational number is also a rational number. 
The right option is D. The sum is a rational expression
