13. -4
14. -6
15. 4
Explanation:

The weight of Priya's cat =
Now, 
The weight of her dog =

Let cat is n times heavy as dog.
Then 

Hence, The cat is 2/3 times as heavy as the dog.
I’m pretty sure the answer is E. X is a linear function. Z is a cubed root function. W is a quadratic function and Y is exponential
7=4w+19
7-19 = 4w+19-19
-12 = 4w
-12/4 = 4w/4
-3 = w
Adding 2x on both side
y+2x=1
