Please help! They are asking for 2 solution sets and I don't know where to start. Thanks in advance!
Solve and write interval notation for the solution set.
3 – 8x < –5 or 3 – 8x > 19
Solve 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]
[-infinity, -2] and [1, infinity]
be the same and equal
(-infinity sign,-2, U(1,infinity sign)
Yes. I should have used parentheses.
It's ok, I see how this is the answer now! Thanks again for your help!
