Answer:
X
Step-by-step explanation:
To be a function, the line has to pass the vertical line test. This means that when a vertical line is passed through every x value, it will only cross the graphed line once.
To help: draw vertical lines through each graph.
In graph W: the line would pass through the top and bottom of the circle - not a function
In graph X: the line passes once through every area - a function
In graph Y: the line passes through the top curve as well as the bottom curve - not a function
In graph Z: the line passes through the curves multiple times - not a function
1) x=6, y=3
2) no solution
Answer:
3x-3
Step-by-step explanation:
You have to combine like terms. <em>x</em> and 2<em>x</em> have the same variable, so this equals 3x, and then you subtract 3 so:
x-3=2x-3-x
=3x-3
