Solve and write interval notation for the solution set.

3 – 8x < –5 or 3 – 8x > 19

**Marth**, Tuesday, July 7, 2009 at 6:07pmSolve each part independently:

3 - 8x < -5

-8x < -8

x > 1

3 - 8x > 19

-8x > 16

x < -2

Therefore, the solution is [-infinity, -2] and [1, infinity]

**Katrina**, Tuesday, July 7, 2009 at 6:23pmWould this

[-infinity, -2] and [1, infinity]

be the same and equal

(-infinity sign,-2, U(1,infinity sign)
