If the question is, what is it? It is called this figure a pencil of lines.
А pencil of lines can consist of any number of straight, the main thing that they all had one common point. Here you can find a lot of vertical angles and rays.
Answer:
6x + 2(−2x + 1) = 22
Step-by-step explanation:
6x + 2(−2x + 1) = 22
This step can be used to solve by substitution method.
I'm not sure what this entire question is, but I believe your answer is:
Symmetric Property.

Answer:
all values of b
Step-by-step explanation:
6b < 36 or 2b + 12 > 6.
First solve the one on the left
6b < 36
Divide by 6
6b/6 < 36/6
b <6
Then solve the one on the right
2b + 12 > 6
Subtract 12 from each side
2b+12-12 >6-12
2b >-6
Divide by 2
2b/2 >-6/2
b >-3
b<6 or b >-3
Rewriting
b>-3 or b<6
b > -3 is an open circle at -3 with a line going to the right
b < 6 is an open circle at 6 with a line going to the left
The or means we add the lines together
We have a line going from negative infinity to infinity
all values of b
Answer:
c. confidence/probability
Step-by-step explanation:
The margin of error of a confidence interval is:
M = T*s.
In which T is related to the confidence level and s is the standard deviation of the sample.
In which
z is the zscore that has a pvalue of 
.
Before the sample is chosen
We choose our confidence level, which will determine the value of T. So the first answer is confidence.
After the sample is chosen
We are 95% sure that the true mean is in the sample. So the second answer is probability.
So the correct answer is:
c. confidence/probability
