-x-y=-5
-x+y=1
adding up the equations gives;
-2x=-4
x=2
replacing in the first equation;
-2-y=-5
-2+5=y
y=3
They would intersect at (2,3)
Answer:
A. Skew lines cannot lie in the same plane.
Step-by-step explanation:
(*Which)
Skew Line Definition (from Wikipedia): <em>"In three-dimensional geometry, skew lines are two lines that do not intersect and are not parallel." </em>-Wikipedia
<em>"Two lines that both lie in the same plane must either cross each other or be parallel, so skew lines can exist only in three or more dimensions."</em> -Wikipedia
Skew lines cannot lie in the same plane so A is correct and C is incorrect.
B and D are incorrect because our friend Wikipedia just said it was incorrect.

Answer:
146 pieces of candy per canister.
Step-by-step explanation:
876 ÷ 6 = 146
The first thing you always do with equations like these is get the y alone by moving everything to the other side. Once this is done, you take the opposite reciprocal of the slope. For example, number a, when you have y alone, is y=-1x+2. So the opposite reciprocal of the slope would be just 1, so the resulting equations would be y=1x+2.
