Answer:
x=-2, y=3. (-2, 3).
Step-by-step explanation:
y=-x+1
y=3
----------
-x+1=3
-x=3-1
-x=2
x=-2
y=-(-2)+1
y=2+1=3
Divide all the terms by 2:
2xy + 12z + 3xy - z
Answer:
0.6°
Step-by-step explanation:
The sum of exterior angles in a polygon is always equal to 360 degrees. For all equiangular polygons, the measure of one exterior angle is equal to 360 divided by the number of sides in the polygon.
360/600=0.6
