Answer 1

(1, infinity)

Answer 2

\[[x/x \in \mathbb{R},x >1]\]

Answer 3

my teacher told me this On your third problem, the numbers in your solution go on forever. They don't stop at 7!

Try thinking about this kind of problem in reverse.

For example, if I had the inequality of x > 5, then my graph would start at 5 ( but not include the 5) and it would go on forever (that would be infinity) to the right.
but im still not getting it!

Answer 4

no my teacher wrote that I dont know how to write the answer!

Answer 5

\[ (5,\infty)\] which means 5 but does not include five "open dot which keeps going" to positive inf
