Answer:
Angle b = 20
Angle c = 160
Step-by-step explanation:
You know this because angle b corresponds with the other 20 degree angle. A line equals 180 so therefore 180-20 = 160.
I really hope this helped

Answer: x = t, y = 2t/3 + 2
Step-by-step explanation:
You want to write both x and y in terms of t
so if you rearrange 4x - 6y = -12 you get
-6y = -4x - 12
6y = 4x + 12
y = 2x/3 + 2
set x = t
and y = 2t/3 + 2
and that's it!
another one you could do is
x = t/2
y = t/3 + 2
or even
x = 3t/2
y = t + 2
i like this one the most because it looks more elegant
