Answer: a
Step-by-step explanation: C is in quadrant 1 and quadrant 1 is (+,+)
Answer:
A. Because the measure of the angle
is
and the angles
and
are Vertical angles. Therefore, they are congruent (
)
B. 
Step-by-step explanation:
<h3> <em><u>The missing figure is attached.</u></em></h3><h3 />
You can observe in the figure that the parallel lines
and
are intersected by a another line
(this is a transversal).
Let's begin with PART B:
Observe that the angles
and
are located inside the parallel lines and they alternate sides of the transversal. Therefore, we can determine that these angles are "Alternate Interior Angles".
Since the lines
and
are parallel, we know that the Alternate Interior Angles are congruent. Then:

Now we can solve the PART A.
Observe the figure.
Since the angle
and the angle
share the same vertex, they are "Vertical angles" and, therefore, they are congruent:

Answer:
3rd graph down
Step-by-step explanation:
greens are x and carrots are y in my equations
2x - y >= 3
x + 2y < 4
The first equation is solid and will highlight everything to the right of it because it is a >
the second is dashed and will highlight everything to the left of it because it is a <
the only 2 graphs that show this are 1 and 3
looking at the points you can see that the points for the solid line are both the same so ignore those and go to the dashed lined ones.
on the first graph the points are (0,4)
plugging those into our equation gives us 0 + 2*4 <4
or 8<4 which doesnt make sense making 3 the correct graph
