How Do I Write a compound inequality to represent all of the numbers between -4 and 6? This unit is Quite confusing, I took lots on notes but still can't understand.

Question

jim_thompson5910 · Answer

if you have two numbers, 'a' and b, such that 'a' is smaller than b

then you can have a third number x in between them like this


a < x < b

jim_thompson5910 · Answer

in this case, x is larger than -4, but it's also less than 6

so we can say

-4 < x < 6

and this means "x is some number between -4 and 6". In this case, we're not including -4 or 6. If we wanted to include either endpoint, you would draw a line under the inequality sign.

It does somewhat make sense, The teacher didn't really elaborate much. But yeah, it is starting to make sense.
