Answer:
A
Step-by-step explanation:
The sum of angles in a quadrilateral is 180
An ordered pair tells you how many units left and right you move (the x
value) and how many units up and down you move (the y value) from the
origin (where the x & y lines meet in the middle). An ordered pair
is in the form of (x, y). Positive x values move right and negative x
values move left. Positive y values move up and negative y values move
down.
Answer: The answer is -5
Step-by-step explanation:
4x - 3 = 6x + 7
- 7 -7
4x - 10 = 6x
-4x -4x
-10 = 2x
---------------
2
-5 = x
-2(y = x - 2) -----> -2y = -2x + 4
y = 2x + 4 --------> + y = 2x + 4
-1y = 8
/ -1 /-1
y = -8
y = x -2
-8 = x -2
+ 2 +2
-6 = x
The answer is ( -6, -8)
