Part A= the starting point is in quadrant 2 and the finishing point is in quadrant 4
is say this because the starting points X and Y value is Neg,Pos there is only one quadrant that has Neg X and Pos Y and that is quadrant 2 and for the finishing point its X and Y value is Pos,Neg and there is only one quadrant that has Pos X and Neg Y and that is quadrant 4
Part A=starting point at quadrant 2 and finishing point at quadrant 4 explanation is above.
Part B= the starting point and the are checkpoint have the same Y and opposite but same X they are equally far form 0 but relative to the finishing point the checkpoint is closer by 2 units on the X axis and the starting point is farther by 2 units on the X axis
Answer:
I believe it’s x but i’m not 100% sure. hope this helps :)
Step-by-step explanation:
The appropriate method to use in solving the given question is permutation. Then, the numbers of ways to arrange the buttons is 1320 ways.
In the given question, the order of arrangement is important, so that the number of ways that Fiona could order the buttons can be determined by permutation method.
i.e 
= 
Red 6
Green 3
Yellow 3
Total 12
Since no two neighbouring buttons of the same colour is allowed, then 3 buttons would be arranged at a time.
Thus, n = 12 and r = 3;
= 
= 
= 
= 12 x 11 x 10
= 1320
Therefore the buttons can be arranged in 1320 ways without two neighbors having the same colour.

Let the unknown number be x.
x × -7 = 7 (x + -40)
-7x = 7x - 280
-14x = -280
x = 280/14
x = 20
Hope this helps!
