Question

write the value of x-5 given that x is in the open interval (4,6)

Answer 1

just sub in the values for x between the interval so 4 -5 + 5-5 + 6-5

Answer 2

What is the definition of an open interval?

Answer 3

an open interval does not include endpoints

Answer 4

The only numeric in the interval (4, 6) is 5. So, solve for \(x - 5 = 5\).

Answer 5

I think it is asking you to list all the possible values of x-5 when x is bound by (4,6). That is just my guess though, since I don't remember having problems worded in this way.

Answer 6

isn't simply

4 < x - 5 < 6

then simplify

Answer 7

That's what I thought it was, but I didn't want to ruin the fun of solving it ^^
