Question

does the inequality x+7>x-4 have no solution, or can x be all real numbers?

how do you graph that? please exlain

Answer 1

\[\Large\rm x+7\gt x-4\]Subtracting x from each side gives us:\[\Large\rm 7\gt-4\]Since our variable fell out of the equation, this expression will either `always be true` or `never true`.

Does the expression look true in this case?
Is 7 larger than -4?

Answer 2

yes

Answer 3

Ok good, so it's true for all x.

Answer 4

Graphing it? Hmm

Answer 5

Do you usually graph on a number line?
Or in x-y coordinate grid?
