Answer:

Step-by-step explanation:
Hello, please consider the following.
We have two equations:
(1) -2x - 4y = 20
(2) -3x + 5y = -25
5*(1)+4*(2) gives
-10x - 20y -12x + 20y = 100 - 100 = 0
-22x = 0
x = 0
I replace in (1)
-4y = 20
y = -20/4 = -5
There is one solution x = 0, y = -5
Hope this helps.
Do not hesitate if you need further explanation.
Thank you

Answer:
See attached image
Step-by-step explanation:
With this type of reflection, one has to convert the points of the form (x, y) into (y, x).
So the vertices of the triangle will transform the following way:
(4, 4) into image (4, 4)
(4, 1) into image (1, 4)
(2, 1) into image (1, 2)
Please see attached picture to find the new reflected triangle depicted in red.
-np-4≤2(c-3)
-np-4≤2x-6
-np≤2x-2
-n≤(2x-2)/p
n≥-((2x-2)/p)
