Answer:
7 1/6
Step-by-step explanation:
So first step, you subtract the two regular numbers like any other subtraction. 15-7 is 8. Now u have 8 - 5/6, so you change 8 into 7 6/6 - 5/6, since 6/6 is still 1. Now since you have a common denominator, you just subtract the fractions and get 7 1/6.

Hello, a sphere has zero vertices.
Answer:

Step-by-step explanation:
Given a function:

To find:
Function
whose graph is a reflection in the y -axis for the given function = ?
Solution:
First of all, let us learn about the reflection of a point (
) in y axis.
For example, let us consider a point (3, 2) on the coordinate axis.
The reflection of this point in y axis will be (-3, 2)
OR
In other words, <em>To find the image of a point in y axis</em>:
the x coordinate is made of negative sign and y coordinate remains the same.
A line is nothing but a number of points joined together.
So, if we want to find reflection of a line or linear function in y axis, we just make the sign of x as negative.
Given that 
We can write it as:

To find its reflection:

Please refer to the attached graphs of
and
.
So, the answer is:
