Point D is rotated 180 degrees using B as the center. Explain why the image of D must lie on the ray BA.
1 answer:
Answer:
The image of must lie on the ray
, since ray
is antiparallel to ray
. That is, the angle between both rays is 180 degrees.
Step-by-step explanation:
Let be the image of
such that
is rotated 180 degrees counterclockwise with
as center of rotation.
must lie on the ray
, since ray
is antiparallel to ray
. That is, the angle between both rays is 180 degrees.

Answer:
the graph on the right-top
Step-by-step explanation:
Transferring an "x" to the right side in , we get
The system of inequalities is
We have y=2x+2 - ascending function with a=2, b=2
b=2 shows that ascending function intersects Y-axis is in y=2 - that situation is only on the right-top and left-down. So, we refuse left-top and right-down.
y=-x-3 - descending function with a=-1, b=-3
y<2x+2 is an area below the ascending function and we see that on the left-
is an area above the descending function
On the left-down we have an area above both functions, so we refuse this picture
Right-top is correct
