Answer:
4
Step-by-step explanation:
The period is the length of one cycle.
By cycle, I mean the smallest piece that can be traced and copied over and over to form the whole graph. If you notice the graph starts at x=0 and the curve makes a complete cycle by x=4. The cycle starts over again at x=4 and ends at x=8. I hope you are seeing the graph looks exactly the same from x=0 to x=4 as x=4 to x=8.
The length of one cycle of this graph is 4.
Please let me know if you have further questions about this question.
Thank you.
Let x = number of questions worth 2 and y be those worth 5.
so we have the system:-
x + y = 50
2x + 5y = 145
multiply first equation by -2:-
-2x - 2y = -100
Add this to the second equation:-
3y = 145-100
3y = 45
y = 15
and x = 50-15 = 35
Answer:- there are 35 questions worth 2 points and 15 worth 5 points.
