On a number line show all values of x that..

1. Have a absolute value greater than 3 ?

2. Have a absolute value less than 3 ?

1.- For the first case we need the absolute value of x greater than 3, this is represented by:

|x|>3

and this has two solutions, one with the positive x and one with the negative x:

solutions to |x|>3:

+x>3

and -x>3 which is x<-3, so combining the two solutions we get:

3<x<-3, in the number line we are going to have two sections, one with the numbers that are greater than 3 and the other with the numbers less than -3 (as seen in the first number line of the attached image).

2.- for the second case we need the absolute of x less than 3, this is represented by:

|x|<3

this also has two solutions (one with the positive x and the other with the negative x)

solutions to |x|<3

x<3

and

-x<3 which is x>-3

combining these two solutions we get

-3<x<3

the number line for this is the second number line in the attached image.

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
