That is the third choice.
If we add the 2 equations we get
2y = -12 so y = -6
substituting in one of the equations we get x = 0
Answer:
To find the perimeter of the triangle, find the lengths of each side of the triangle using the distance formula. Use the distance formula to find the length between point A and B, B and C, C and A. Then add all three lengths together to get the perimeter.
Step-by-step explanation:

Answer:
The margin of error is 
Step-by-step explanation:
From the question we are told that
The sample size is 
The sample mean is 
The standard deviation is 
Given that the confidence level is 95% the the level of significance can be evaluated as
Next we obtain the critical value of 
from the normal distribution table,the value is 
Generally the margin of error is mathematically represented as
substituting values
