Let x represent the number.
.. x^2 +x = 2
.. x^2 +x +1/4 = 9/4 . . . . add 1/4 to complete the square
.. x +1/2 = ±3/2 . . . . . . . .square root
.. x = -2, 1
Numbers meeting that requirement are -2 and 1.
I can't draw the graph, but I will give all needed information to be used to draw the Box Plot.
1st arrange the data from smaller to greater:
53 55 56 56 57 57 58 58 58 59 59 60 62
|------------------|-----------------|----------------|-----------------|
Min Q₁ Median Q₃ Max
Data Range = 62 - 53 = 9
Minimum = 53
Q₁ = 56
Median = 58
Q₃ = 59
Maximum = 62
While working your Box Plot, follow the info given BY ORDER, the way I displayed them
Step-by-step explanation:
We know that...
x+y (from the first pair) corresponds to 8(in the second pair)..
0 (from the first pair) corresponds to x-y (in the second pair)..
Hence,

By simply adding the two equations we get,

Hence,
By substituting x=4, we get that y=4
Hence,
x=y=4
