It's been a while since I have done these kind of questions, but I would say a 180 transformation would be my best answer. Hope this helps a bit!
Answer:
A. The mean is increased by 3
Step-by-step explanation:
2 + 9 + 11 + 10 + 3 + 5 + 4 + 12 = 56/8 = 7
2 + 9 + 11 + 10 + 3 + 5 + 4 + 12 + 34 = 90/9 = 10
10 - 7 = 3
The slope is 5/3 and the y- intercept is -2/3
For this case we have the following system of equations:
We multiply the first equation by -5:
Thus, we have the equivalent system:
We add the equations:
We find the value of the variable "x":
Thus, the solution of the system is:
