After reflecting the points of triangle GHI over the y axis, the new points will be:
G' (3,0)
H' (5,-5)
I' (-1,-5)
Answer:
C
Step-by-step explanation:
This is a combination question.
In the first instance, we select 5 from 20 and in the second case , we select 4 from 20.
The total number of ways to solve the first instance is 20C5 = 15504 ways
The total number of ways to solve the second instance is 20C4 = 4,845
The ratio of the first to the second scenario is 15,504/4,845 = 3.2 = 16 to 5
<em>p = 21</em>
Step-by-step explanation:
When you have a midsegment, the base is going to be two times as large as the midsegment. You can find the midsegment if you multiply it by two and set it equal to the base. I have attached a photo below that may help you.
This is the equation we will be using.
![2(p-13)=p-5](https://tex.z-dn.net/?f=2%28p-13%29%3Dp-5)
Now let's solve! Let's start by distributing the 2 by what's in the parentheses.
![2p-26=p-5](https://tex.z-dn.net/?f=2p-26%3Dp-5)
Subtract p from both sides.
![p-26=-5](https://tex.z-dn.net/?f=p-26%3D-5)
Add 26 to both sides.
<u>p = 21</u>
Two, 2 and 7, because 3/11 just equals 0.2727272727..., so the two and seven keep repeating
