Answer:
No
Step-by-step explanation:
For a point to be a solution of a system of equations, it has to work for both equations in said system. For this particular point, it doesn't fit into both.
12=5(2)+2
12=10+2
12=12
4(2)-12=0
8-12=0
-4=0
The second equation doesn't work out.
Answer: Y=0 for sure, I'd need a more exact graph to tell you other ones.
You might get away with 0<=y<4
Step-by-step explanation: Asymptote is anywhere the graphs will never cross,
Answer:
x = - 6
Step-by-step explanation:
Given
= 3
