Step-by-step explanation:
Answer: The system of equations has NO SOLUTION.
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:

Where "m" is the slope and "b" is the y-intercept.
Given the following system of equations:

Write the first equation and solve for "y" in order to express it in Slope-Intercept form:

You can identify that:

Apply the same procedure with the second equation. Then:

You can identify that:

The slopes of both lines are equal, therefore the lines are parallel and the system has NO SOLUTION.

Answer:
2.0
Step-by-step explanation:
Couldn't really understnd what you wrote but I'll assume it's the standard deviation of a fair, 7-sided die
The standard deviation is just the square root of the variance (which is just the second moment minus the first moment squared)
The first moment (AKA the average is..)

The second moment is..


Step-by-step explanation:
=> x + 80 + 20 = 180
=> x + 100 = 180
=> x = 180 - 100
=> x = 80°
