Answer:
A. True
Step-by-step explanation:
Inspect the graph to see if any vertical line drawn would intersect the curve more than once.
If there is any such line, the graph does not represent a function.
Answer:
x=-1, y=3
Step-by-step explanation:
3x+2y=3
3x-2y=-9
since we have -2y and 2y we can just add the equations
6x=-6
x+0y=-1
x=-1
to solve x using elimination multiply the top equation by -1
-3x-2y= -3
3x-2y=-9
and add
0x-4y=-12
-4y=-12
y=3
and substitute x and y to double; check
3(-1)+2(3)=3
-3+6=3
3=3
checks out so these are correct
