Hey there!
I just worked it out and the answer is D. 4y^2-10y-1
I’ve just studied these long equations and then having to simplify the expressions in algebra. I really hope my answer benefits you in the best way!

Answer: 2 cakes and 2 slices of an extra ( assuming its cut into 10 slices)
Step-by-step explanation:
11 divided by 5 is equal to 2.2
in this case, 11 cakes divided by 5 friends is equal to 2 cakes and 2 slices.
normally you would just give them 2 cakes each (if you had 10 cakes) but you have 1 left over. So unless Sako wanted a cake as well, that's the answer(if she did, it would only be 2 cakes, no extra slices).
For this case we have a direct variation of the form:
Where "k" is the constant of proportionality. To find it, we use the following data:
Substituting:
Clearing the value of k:
Thus, the direct variation is given by:
For
we have:
Answer:
The value of the direct variation for is: 
Is this all there is to the question????
You can multiply 10 by 1/4 or .25
10x.25=2.5
