The equation that does not assign one value to y is
and the points that do not represent a function is (c)
<h3>The equation that does not assign one value to y</h3>
To do this, we simply make y the subject of formula.
So, we have:
![\frac 5y = 7x + \frac{10}{2y}](https://tex.z-dn.net/?f=%5Cfrac%205y%20%3D%207x%20%2B%20%5Cfrac%7B10%7D%7B2y%7D)
Simplify
![\frac 5y = 7x + \frac{5}{y}](https://tex.z-dn.net/?f=%5Cfrac%205y%20%3D%207x%20%2B%20%5Cfrac%7B5%7D%7By%7D)
Subtract 5/y from both sides
![0 = 7x](https://tex.z-dn.net/?f=0%20%3D%207x)
Rewrite as:
![x = 0](https://tex.z-dn.net/?f=x%20%3D%200)
This means that the value of x is 0 irrespective of the value of y
Hence, the equation that does not assign one value to y is ![\frac 5y = 7x + \frac{10}{2y}](https://tex.z-dn.net/?f=%5Cfrac%205y%20%3D%207x%20%2B%20%5Cfrac%7B10%7D%7B2y%7D)
<h3>The points that do not represent a function</h3>
For a set of point to represent a function, the points must represent a one-to-one or many-to-one relationship.
From the list of options, option (3) represents a one-to-many relationship.
This is so because one x value has 3 y values
Hence, the points that do not represent a function is (c)
