please help me solve this. what is the equation for this?
When writing down the inequalities from a number line, you need to look for two things first. If you see hollow dot, it means you need to use “<”or " >”. However, if you see solid dot, you need to use " ≥" or" ≤"
According to your question, the line is tied with two different numbers that's between those numbers. The line between two numbers mean they are included, but different inequality sign.
It says using "X" as the unknown. That's your unknown variable

yeah but idk what inequality sign to use for it
its supposed to be like this 'number. inequality sign, x , inequality, sign, number'

but idk what inequality sign to put

Look at your number line. What dots do both of the numbers have? Hollow or solid dot? Once you figure it out, write down the numbers and then the signs between the two of the inequalities. Both should have different inequalities in this number line.

ok yeah i dont think yk what i meant

ok yeah i dont think yk what i meant
did you figure it out?
obsidian wasp
nope
turbid marsh
ok, you basicly have to give an interval where for the values x can have
e.g. if i say my x has to be between -2 and 2
i say -2 < x < 2
and in this case the line above the line with the numbers is supposed to show which values x can have
it doesnt really have something to do with equations this time
obsidian wasp
yeah ik but its the signs where idk if i should use >= this sign on it or not or just > or smth like that
no wait actually i got it because i just looked at how i did my other old question
the answer is this
turbid marsh
the answer is this
Yup, good job 👍
turbid marsh
yes, i would have done it just like you did

or it could have also been expressed as
x ε (-4 , 3 ] .

didnt have the the option to do that but thx
obsidian wasp
yes, i would have done it just like you did
ohh right i see
warped zinc
Yup...just an alternative if inequality wasnt a compulsory
obsidian wasp
ohhh i see
