Answer:
y= 6971 -7 x  OR y = -7x + 6971
Step-by-step explanation:
the 6971 is the original number you started with, you are now decreasing by 7, so you use the value of -7. The x is the number of years that pass by, so the variable x affects the number 7 because it says decreases by 7 per year. The x does not go with 6971 as that number doesn't get directly affected. 
 
        
                    
             
        
        
        
Hello!
We are given the weight of Mia's dog and told to find the weight of Lettie's dog based on the known relationship. Using these given values, we can create the following equation (let "w" represent the total weight of Lettie's dog):
w = 32.6(3.8)
Simplify the right side of the equation:
w = 123.88
We have now proven that Lettie's dog weighs 123.88 lbs.
I hope this helps!
