Question

How do you solve and graph `-0.1<=3.4x-1.8<6.7` ?

Answer 1

Given: `-0.1<=3.4x-1.8<6.7`

Add 1.8 to everything:

`1.7<=3.4x < 8.5`

Divide everything by 3.4:

`1.7/3.4<= x < 8.5/3.4`

Simplify the fractions:

`1/2 <= x < 5/2`

Graphing instructions:

Put a point on the x axis at `1/2`
Put a very small circle (to indicate that it is not included) on the x axis at `5/2`
Draw a line segment between the point and the small circle.
