2y - 8 = 6x
2(3x + 2) - 8 = 6x
6x + 4 - 8 = 6x
6x - 4 = 6x
-4 = 0
this system has no solutions
Reflecting is pushing it across from one side to another.
The answer would be (7,6)
Sorry I'm late.
Answer:
use sin to find the angle x
<span>A=1/2(a+b)h for h.
First, you need to get rid of 1/2, so divide both sides by 1/2.
A/(1/2) = (a + b)h
You can simplify the </span>A/(1/2) by multiplying by the reciprocal of 1/2, so 2/1.
2A = (a + b)h
Now divide both sides by (a+b).
2A/(a+b) = h
