Solve and express in interval notation
Solve: 5 – 8x > 11 and write interval notation for the solution set. This is what I get but I need it in interval notation.
x<3/4 or x >2
Solve: (x3)/(x^225)<0 and write interval notation for the solution set.
This is what I get for this one but I need it in interval notation.
x<5 or 3<x<5

The answers are correct.
To represent disjoint intervals in interval notation, we only need to join each interval using a "union sign", or ∪.
So the required answer would be:
(∞, 3/4) ∪ (2, +∞)
Parentheses have been used in the above cases (instead of square brackets) because in each of the 4 cases, the values of the limits are to be excluded from the interval. 
Thank you!
