Required
Determine the error in the plot
The plot on the attached graph is represented with: 
This implies that Raj plotted the x coordinate on the y coordinate and vice versa.
Hence: (c) is true
Answer:
(x,y)=(0,-23)
Step-by-step explanation:
Answer:
What option are you talking about for, is it for your quiz or for your classwork
<span>Each team in the softball league plays each of the other teams exactly once. For every game, there is 2 team playing. The order is not important because A vs B is same as B vs A
So you just need to makes a combination of 2 that have a result of 21. If there is t number of teams, the number of matches would be:
tC2 = t!/2!(t-2)! = 21
</span>t! / (t-2)! = 21 *2
(t)(t-1)= 42
t^2 -t -42=0
(t-7)(t+6)
t=7 ; t=-6
Excluding the minus result, you got 7 teams.
Multiply the first equation by -2 gives:_
-2y = -8 + 2x
2y = 8 - 2x
adding these 2 equations:-
0 = 0
This shows that the 2 equations are equal so there are infinite solutions
