To get the function form, the y must be the only variable on one side. So, we need to solve for it.
We have:
-x + y = 6
then we get
y = 6 + x
when we move the x to the other side to get y by itself.
If you have any questions then leave a comment. Good luck!
Hello!
Reading these types of graphs can be difficult, but it displays the following numbers:
27, 30, 31, 43, 45, 49, 51, 58, 62, 64
To find mean, or average, you need to add up all of the numbers and divide by how many there are (10)
This will give you 46.
I hope this helps you and good luck!

In the first generation we have 2 ancestors.
In the second generation we have 4 ancestors or

ancestors.
In the third generation we have 8 ancestors ot

ancestors.
We can see that each succesive generation has two times more members. The sum is:

To calculate number of ancestors we can use formula <span>for the sum of a geometric sequence. Geometric sequence is sequence of numbers that differ by a certain factor. This factor is called ratio. Formula is:
</span>

<span>Where:
S -> sum
a1 -> first member of a sequence
r -> ratio
n -> number of elements
For this question:
a1 = 2
r = 2
n = 40
</span>

<span>
b.
1 generation = 25 years
40 generations = 40 * 25 = 1000 years
c.
Total number of people who have ever lived = </span>

Number of ancestors in 40 generations =

The number of ancestors is greater than total number of people who have ever lived. This means that not all ancestors were distinct and that in each generation both men and women had children with more than one partner.
Answer:
The Circle on the Top right doesn't belong since every other circle has a green quadrant, whereas on the other hand the circle on top right is missing the green quadrant
Hope this helps!
