Answer:
No solution
Step-by-step explanation:
If we substitute the y into the equation, we get 9x+3(-3x+4)=-7
If we distribute the 3, we get 9x-9x+12=-7
This then cancels out both 9x's and we are left with 12=-7, making it no solution.

Answer: Zack won. If you compare the decimal equivalents of their scores, -3.666 < -3.625
Step-by-step explanation:
Given: Vanessa and Zack are playing a game where the player with the lower score wins.
Score of Vanessa=
Score of Zack =
We can see
⇒ Zack has the lower score .
Hence, Zack won. If you compare the decimal equivalents of their scores, -3.666 < -3.625.
You need to sub your X and Y values in. Take (-1,-3) for example: if you sub in these values, your equation y=-2x -1 will become (-3)=-2(-1) - 1. However, if you simplify it out, you'll realise that it doesn't make sense as you'll get -3=-1 which is clearly untrue, thus (-1,-3) is the only pair that doesn't satisfy your function.
