    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.

    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.

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

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

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

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

    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.

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

    as they both affect the outcome

    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 >.<

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

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

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