Answer:
C. 15
Step-by-step explanation:
The team has won ...
0.80 × 15 = 12 . . . games
To finish the season with a 90% winning percentage, they must win a total of ...
0.90 × 30 = 27 . . . games
That is, they must win ...
27 -12 = 15 . . . more games
The team must win 15 more games to finish with a 90% win rate.

<em>Additional comment</em>
That means they must win every game of the last 15 played.
The slope can be worked out by the equation:
So with the coordinates (1,2) and (-2,4):
x1 = 1 y1= 2 and
x2 = -2 y2 =4
Note that x1 and y1 use the same coordinate, vice versa with x2 and y2.
Tip: The equation can be y1-y2 and x1-y2 too (have a think why)
So the answer is 2/-3, which is the same as C)
-2/3
Answer:
(-5.5, 3)
Step-by-step explanation:
There is no solution. The first step to solving the equation is distributing the 6 into the x-1, and after that the equation looks like this: 6x-1=6x-1, which, if you were to finish solving the equation, would end up being 0=0, or in other words <em>no solution. </em>
