He chose the right type of equation equation, but the equation should be y=15/x
If one zeros is x= -7 then the other zero is x=5
Step-by-step explanation:
We are given the function: 
If one zeros of the function is x=-7 we need to find other zero of the function.
We can find zeros of the quadratic equation by factorizing the equation

Factorizing the quadratic equation:

So, if one zeros is x= -7 then the other zero is x=5

You need the starting point, and another point that helps direct where the ray is aimed. Call these two points A and B.
Saying "Ray AB" means we extend a line through AB such that the line goes forever through B and beyond B, but we do not do the same for point A. The point A is effectively a cliff where no road goes on the other side of it. Check out the diagram below to see what I mean. The arrow means the line goes on forever in that direction.
Let x be the number of pages of advertisements.
