Answer:
Number of ways: 3
Step-by-step explanation:
Hill grove High School plays 3 soccer games.
The team loses 2 of those games.
Total number of games played = 3
Number of games loose, L = 2
Number of game won, W = 1
<u>Possibilities:-</u>
- First game won and last two loose, WLL
- Second game won and first and last loose, LWL
- last game won and first two loose, LLW
Please find attachment for tree diagram.
Hence, Total 3 ways this would happen.

Answer:
see graph of y = 5x - 7
Step-by-step explanation:
If graphing is the task, you should rewrite the equation in a y = ax + b form. All straight lines can be described in this form, only the a and b determine which line it is.
Your equation 5x-y=7 has the 5x on the left side, so lets move it to the right. It will get a negative sign (this is the same as subtracting 5x like you did in your picture)
5x - y = 7
-y = 7 - 5x
Now we still have the -y which should be a +y. So we multiply left and right with -1 and get:
y = -7 + 5x
If we swap the -y and 5x (we can, because they are just an addition), we get:
y = 5x - 7
Now the equation is in its "normal" form. It's like the y = ax + b with a and b chosen as a=5 and b=-7.
The normal form is handy because you can immediately see the slope is 5 and the intersection with the y-axis is at y=-7.
