Answer:
I had a slightly different question, but I think its option D
(x - 3)(x + 3)
Total number of ways to make a pair:
The first player can be any one of 7 . For each of those . . .
The opponent can be any one of the remaining 6 .
Total ways to make a pair = 7 x 6 = 42 ways .
BUT ... every pair can be made in two ways ... A vs B or B vs A .
So 42 'ways' make only (42/2) = 21 different pairs.
If every pair plays 2 matches, then (21 x 2) = <em><u>42 total matches</u></em> will be played.
Now, is that an elegant solution or what !
Its y=4x+23, yeet on my feet, apex is a defeat
Answer:
y = -6
Step-by-step explanation:
On the coordinate plane, the vertical axis (up and down) is the y-axis and the horizontal axis (side to side) is the x-axis. However, when there is a horizontal line on the graph, it represents a value of y that is true for any value of 'x'. In the same respect, a vertical line is a value of x that is true for any value of 'y'. In the case of the point (5, -6), a horizontal line would have to be y = -6 in order to pass through the point and cross the coordinate plane from left to right.
Z=3y+x
if you follow all the steps and move all the other values on one side, you can find z!
