The first and last choices are right. Explanation below:
---
The "<" sign represents less than, meaning the ray will move to the left (and vice versa). Since there is no line underneath the sign, the graph of x<5 will use an open circle.

So you have: ((-15(x^2)(y^6))+(50(x^4)(y^3))+(20x^2y))/((5x^2)(y))
which simplifies to
(-3y^5)+(10(x^2)(y^2))+4
as there are no like terms and x and y have not been given, this is as far as it can be simplified.
I’m going to put them in order as the picture shows :)) hope this helps!!
