Answer:
-2
Step-by-step explanation:
-1+2-3

Z = 140
X = 40
Y = 40
Explanation:
Z and the angle given (140 degrees) are vertical angles, and are therefore congruent
We know that x and y are vertical angles, so they are also congruent to each other
You know that together, the angles have to add up to 360
140 + 140 + x + y = 360
Another way of putting it:
360-280 = 80
Now, we have to divide by two since we need to find x AND y
80/2 = 40
Therefore, your answers for x and y are 40
To double check, you can add up the angles and see if they equal 360
140 + 140 + 40 + 40
280 + 80 = 360
C) r^2 + 1 because any number squared (positive or negative) will be positive
Answer:

Step-by-step explanation:
The solution to the equations is at the point of intersection of the 2 lines.
If the system has no solution, this indicates the lines do not intersect and therefore must be parallel.
Answer:
x = 13
Step-by-step explanation:
3x + 2x + 5 = 60
5x + 5 = 60
5x = 65
x = 13
