Question

Need to know this asap number 6 and 7

Answer 1

The equation that does not assign one value to y is $\frac 5y = 7x + \frac{10}{2y}$ and the points that do not represent a function is (c)

The equation that does not assign one value to y

To do this, we simply make y the subject of formula.

So, we have:

$\frac 5y = 7x + \frac{10}{2y}$

Simplify

$\frac 5y = 7x + \frac{5}{y}$

Subtract 5/y from both sides

$0 = 7x$

Rewrite as:

$x = 0$

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 $\frac 5y = 7x + \frac{10}{2y}$

The points that do not represent a function

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)
