Hi there.
They are basically asking how you could change the graph in a way so that the change in wins isn't as noticeable. This can be done by starting at zero number of wins on the y-axis.
Answer:
(3, -2)
Step-by-step explanation:
It is where the two lines on the graph intersect.
Answers:
- x = 21.25
- y = 22.5
- z = 23.75
=============================================================
Work Shown:
AP = arithmetic progression, which is the same as arithmetic sequence
d = common difference
- x = 20+d
- y = 20+2d
- z = 20+3d
Notice how we scale up the d terms d, 2d, 3d, counting up by 1 each time.
So that must mean 25 is the same as 20+4d
20+4d = 25
4d = 25-20
4d = 5
d = 5/4
d = 1.25
and therefore,
- x = 20+d = 20+1.25 = 21.25
- y = 20+2d = 20+2*1.25 = 22.5
- z = 20+3d = 20+3*1.25 = 23.75
We could convert these to fraction form, but I find decimal form is easier in this case.
I think that the answer is the 2rd choice on the 2nd picture.
Hope this helps!! :-)
6ba is the answer you need
