Answer:
m<6 = 130°
Step-by-step explanation:
If m∠2 = 130°, what is m∠6?
Find the diagram attached
From the digram we can see that the vertical lines are parallel. Hence based on geometry;
m<2 = m<6 (corresponding angles)
Given m<2 = 130°, hence m<6 = 130°

Answer:
(x, y) = (-1, -3)
Step-by-step explanation:
The equations are "consistent" and "not dependent." This will be the case whenever the ratios of x- and y-coefficients are different.

We can solve this by "elimination" by multiplying the first equation by -4 and adding the result of the second equation being multiplied by 7.
-4(2x -7y) +7(7x -4y) = -4(19) +7(5)
-8x +28y +49x -28y = -76 +35 . . . . eliminate parentheses
41x = -41 . . . . . simplify
x = -1 . . . . . . . divide by 41
Using the second equation, we find y to be ...
(7x -5)/4 = y = (7(-1) -5)/4 = -12/4 = -3
So, the solution is (x, y) = (-1, -3).
