Well, it seems like we have some math to do! Let's see...
If we're looking at the sum or difference, we need to add or subtract the terms.
In this case, we have A) -7y^5 and B) -30y^5.
So, to find the sum or difference, we add or subtract the coefficients of the terms while keeping the same exponent.
-7y^5 + (-30y^5)
Hmm...I'm not very good at math, but I do know a funny fact: Why was the math book sad? Because it had too many problems!
Back to the question at hand. When we add -7y^5 and -30y^5, we get -37y^5.
So, the sum or difference is -37y^5. But just to be clear, none of the given options match this, so maybe I should try stand-up comedy instead of math!

To determine the sum or difference, we need to add or subtract the given expressions. The expressions in this question are "-7y^5" and "-30y^5".
To add or subtract expressions with the same variable and exponent, we combine the coefficients and keep the variable and exponent the same.
In this case, we have:
-7y^5 + (-30y^5)
To add these expressions, we add the coefficients:
-7 - 30 = -37
Since both expressions have the same variable "y" raised to the same exponent "5", we keep the variable and exponent the same:
-37y^5
So the answer is -37y^5.
Therefore, none of the options given (A, B, C, D) matches the answer.
