$2x + 5 > -3$ and $3x - 4 \leq 5$

Well this is what i have: $x > -4$ and $x \leq 3$

but im not sure how to graph it or put it in interval notation.

Thanks for the help.(Nod)

Thank you so much.

just wondering though. what if it said 'or' instead of 'and'?

that'd mean that "it happens one thing, or, it happens the other thing."

how would you show it as a interval or a graph?
