Answer:
![\displaystyle [-7, -7]](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5B-7%2C%20-7%5D)
Step-by-step explanation:
{2x - 6y = 28
{−x - y = 14
−⅙[2x - 6y = 28]
{−⅓x + y = −4⅔
{−x - y = 14
____________

[Plug this back into both equations above to get the y-coordinate of −7];

Method 1
----------------------------------------------------------------
Since the numerators are the same, the smaller the denominators, the greater the fraction is.
Arranging from the least to the greatest

----------------------------------------------------------------
Method 2
----------------------------------------------------------------
Lets change all to the same denominators



Now that all the denominators are the same, we can arrange the fractions by comparing the numerators. The bigger the numerators, the greater the fraction.

Answer:
50 degrees
Step-by-step explanation:
because it is a parallelogram, angle B = angle D, and angle C = angle A
that means we have 130(2) = 260 degrees that we know.
the total interior angles of a parallelogram = 360
360 - 260 = 100 degrees left. BUT because those are the total amount of angles left, those are angles A and C combined, so you have to divide 100 in half to get the angle A/ angle DAB
100/2 = 50 degrees. hope this helps! leave a question if you are still confused.
