Answer:
   Both expressions should be evaluated with two different values. If for each substituted value, the final values of the expressions are the same, then the two expressions must be equivalent.
Step-by-step explanation:
Both expressions are linear expressions. It takes 2 points to define a line. If the lines defined by each expression go through the same two points, then the expressions are equivalent.
If the expressions have the same value for two different variable values, they are equivalent. (choice D)

<em>Additional comment</em>
One more point is needed than the degree of the polynomial expression. That is, quadratic (degree 2) expressions will be equivalent if they go through the same 2+1 = 3 points.
 
        
             
        
        
        
Well, if it starts on 11:00 am, add 4 hours = 3:00 + 5 min = end time = 3:05 am.
Hopes this helps ;)
        
                    
             
        
        
        
The slope of a line is always zero because the line does not move up or down on the y-axis.
 
        
                    
             
        
        
        
Answer:
3 cans
Step-by-step explanation:
We need to find the area of the deck
A = 9 1/9 * 3
Changing to an improper fraction
9 1/9 = (9*9+1)/9 = 82/9
A = 82/9 *3 = 82/3
Changing back to  a mixed number 
82/3 = 27  1/3
Each can covers 10 m^2 
We will need 3 cans
 
        
                    
             
        
        
        
Answer: B
Step-by-step explanation: if you divide 27/30 by 3 you get 9/10
