Question

PLEASE HELP
How can I graph the inequality:
 x+15>95

john_es · Answer

$$x>95-15\Rightarrow x>80$$
Draw a line (the real number line) that begins in 80, and continue to the infinity (you indicate this using an arrow pointing to the right).

Where did you get the 80?

john_es · Answer

You solve for x the inequality in order to graph it. So, 
$$x+15>95\Rightarrow x+15-15>95-15\Rightarrow x>80$$

anonymous · Answer

Ok but f I add 80 to 15 I get 95 and that is not greater than 95?

john_es · Answer

Yes, you cannot add 80 to check it, because the inequality says x>80, it means, numbers greater than 80 (but not equal). For example, you can check it with 81 or 80.0001. Both numbers are greater than 80.

Okay thanks! I get it know

john_es · Answer

You're welcome.

anonymous · Answer

Wait how would I explain this graph??

john_es · Answer

You explain this graph, saying that only those numbers greater than 80 (lying at the right or in the side where the arrow points) satisfy the inequality proposed.
