How to represent this inequality in a line graph or interval notation?

Question

The original inequality was -2x<3-x<(or eqaul to) 8

so I found that x> (or equal to) -5

and x>-3

How would I represent this in interval and set builder notation, using -inf and inf for infinity

Answer 1

You solved it incorrectly. The right answer is -3&lt;x&lt;(or equal to)8. In interval notation, it&#039;s: (-3, 8].

(The bracket and parentheses are important.)
