Answer:

Step-by-step explanation:


- In order to combine these two equations, an idea you need to keep in mind is finding a way of setting these equations as equal to each other. I saw that each equation shared a common value,
. In this case, we need to isolate
in the first equation so that both equations
.



- With this, we now know that both
and
are equal to
, so we can set them equal to each other.



- Reply to this if anything I'm saying or doing is confusing in any way, or if you find a mistake. :) Solve for
.







- Hopefully this answer is correct AND makes sense in terms of how I achieved it. Again, reply to this with any questions or mistakes I made and I'll do my best to answer or fix them.
If you solve for theta, it would be 3pi/4
Answer:
yes
Step-by-step explanation:
The answer is yes because I need points to ask a question
The new coordinate of point B would have to be (-1,5). This can be seen when graphing the coordinates you gave, and by substituting 1 for -1 in the coordinates of point B into that same graph
