Answer:
See below.
Step-by-step explanation:
You take the absolute value of the negative number and add.
For example the difference between - 2 and + 3 is |-2|
= 3 + 2 = 5.
+4 and - 6: we have 4 + |-6| = 10.
Answer:
yes it is
Step-by-step explanation:
since 25 is less than 26
I believe there would be 6 more girls than boys.
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)
