## jennyrlz one year ago Some college algebra :D

Identify the correct statements about "2n ≥ 100." This is a proposition. This is not a proposition. Its truth value depends on the value of n. Its truth value depends on the value of 2n.

2. jennyrlz

i thnk its a c and d

3. jennyrlz

it is a roposition... i think...

6. jennyrlz

hey :)

7. zepdrix

eyy c:

8. jennyrlz

:D

9. jennyrlz

what do you think of this question?

10. jennyrlz

im having some trouble the concept of what is a propisition

11. jennyrlz

atleast when it comes to an actual equation hahaha

12. jennyrlz

some trouble grasping*

13. jennyrlz

if you can explain with other examples it would help a lot :D

14. jennyrlz

as i have 80 more questions to go ^.^

15. zepdrix

An Axiom is something that we take for granted. We just assume that it is true. It's like one of our basic building blocks that we use to do other things. Like ummm.. maybe an example of an axiom: Through any two points, there is exactly one line. That is simply how we define a line. A proposition on the other hand, is something that we propose. It may or may not be true.

16. jennyrlz

ok.... im on the same page for now c:

17. zepdrix

An example of a proposition: $$\large\rm 5x\ge10$$ This proposition is true for only certain values of x. Namely, $$\large\rm x\ge2$$.

18. jennyrlz

so then 2n>/_100 is a proposition that may not be true correct...

19. zepdrix

Mmm ok good :d it's a proposition. It will only be true for certain values of n.

20. zepdrix

Hmm those last two options have me confused :d thinking

21. jennyrlz

22. jennyrlz

what has me confused is the first two options :/

23. jennyrlz

because both n and 2n are importand factors that affect the "truth"

24. jennyrlz

i think....

25. zepdrix

The first two? Oh, well remember our definition for proposition, it can be true or false. So whether or not the proposition is true or false, it's still a proposition, ya? :) It's either a true proposistion, or a false proposition, depending on what m is.

26. jennyrlz

ok :D

27. jennyrlz

but the last two options are two sides of the same coin

28. anonymous

Well if you know the value of n, you know the value of 2n so it is a bit redundant...

29. jennyrlz

as they both affect the outcome

30. jennyrlz

we dont know the value of n... xD

31. anonymous

Well yeah.. I said 'if"

32. zepdrix

I would lean towards the last option, The entire quantity 2n is what determines the truth of the inequality. But ya, it's worded a little strangely >.<

33. jennyrlz

but cant it be both?

34. zepdrix

Oh :) hmm

35. jennyrlz

its not a one choice answer

36. jennyrlz

it is a "which apply" type of question

37. anonymous

If the 2 was taken away it would be a completely different inequality so the last one makes more sense.

38. zepdrix

It's certainly A, D But you're saying maybe A, C, D. I dunno :) sorry. This one has me a little confused lol

39. zepdrix

I think it's just A and D, But you might be right :O

40. jennyrlz

ill go with you... as i am lost for now xD

41. jennyrlz

it was just d, but thanks for the help :D

42. jennyrlz

ill ask for more help :P

43. zepdrix

It was just D? Not A? 0_o

44. triciaal

my choice would be C need to know n to determine 2n before true or false

45. jennyrlz

it was just d xD, i dont understand it either...

46. jennyrlz

like it has to be one or the other it is and is not a proposition...?

47. zepdrix

lol weird :)
