Question

Solve each inequality and graph the solution set on a number line X+1<5

Answer 1

x + 1 < 5 -- subtract 1 from both sides
x < 5 - 1
x < 4

open circle on 4, shading to the left.

Learn this and it will help you in the future :
if the inequality contains an equal sign, then it is a closed circle
if the inequality has no equal sign, then it is an open circle
< (less then) means shading to the left
> (greater then) means shading to the right

Answer 2

you solve inequalities pretty much like equations except for when inequalities are divided/multiplied by a negative number, then the inequality sign changes

Answer 3

@kelliegirl33 Closed circle? Is that the same as a solid line?

Answer 4

you are talking about graphing on a graph and not a number line.
On a graph, if there is an equal sign, then it is a solid line
If there is no equal sign, it is a dashed line

Answer 5

@kelliegirl33 Oh ok. I was thinking of the wrong thing. Thanks

Answer 6

no problem :)
