Answer:
Choice B is correct
Step-by-step explanation:
The variable x represents the number of hours;
2, 4, 5, 7, 9
The least value is 2 while the maximum value is 9. The scale to be used must accommodate all these values. The scale can thus begin from 0 to 10. Choice A is incorrect since the values 7 and 9 will not be accommodated in the graph.
The y variable represents the number of pages read;
50, 100, 125, 175, 225
The least value is 50 while the maximum value is 225. The scale to be used must accommodate all these values. The scale can thus begin from 0 to 250. Both choices C and D are incorrect since none of the values will be accommodated in the graph.
- I’m assuming the expression implies the following:
(1-n)/(n^2 - 1)
The steps goes as follows:
= -(n-1)/(n^2-1) (factored a negative out)
= -(n-1)/[(n+1)(n-1)] (Factored denominator into a difference of squares, but don’t just blindly accept the fact, expand it and you should get the original denominator)
At this point, the (n-1) terms cancel, as you should know: a real number, besides 0, over itself is 1.
= -1/(n+1) , which is the answer
Note: You could also see it as 1/-(n+1) or 1/(-n-1)
Which relation is displayed in the table? {(3,3), (3, 7), (5, 8), (9,0)} {(3,3), (7, 3), (8, 5), (0,9)} {(3,3), (3, 7), (5, 9)

Answer:
{(3,3), (3, 7), (5, 8), (9,0)
Step-by-step explanation:
The first number of an ordered pair is the x value and the second number is the y value.
