ANSWER

EXPLANATION
If ABCD is a parallelogram, then
line AB is parallel to line DC .
This means that,

and

are alternating angles.
Alternate angles are congruent.
This implies that,

We group like terms to obtain,

This simplifies to,

Also, if ABCD is a parallelogram then,
BC is parallel to AD. This means that,

We group like terms to get,

This simplifies to,

We divide both side by 4 to get,
Answer:
0
Step-by-step explanation:
The first thing to do in this case is to graph both equations
y = 2x +1
y = / x /
Once graphed, you must evaluate points in the Cartesian plane that satisfy the inequations to know where the solution set is.
For this case, the solution set is in the shaded region, or equivalently, quadrants 1 and 2.
answer quadrants 1 and 2.
