2. Which graph represents x < - 7.7

2. Graph D

3. Solve: 6(x + 3) + 1 = - 114

4. - 10 < 3x + 2 < 14

A compound inequality with 'or' is true if one or both statements are true. The solution can be a combination of both inequalities or only one.

2x+ 1 < 11 or x > 3x + 2

2x < 10; x < 5

-2x > 2; x < -1

Since the second inequality is part of the first inequality, ( x < 5 includes x <-1), the solution is the first inequality. {x| x < 5}

-2 > x + 1 or x + 2 > 3

-3 > x; x < - 3 or, x > 1

There isn't a number that is both less than - 3 and greater than 1. But with inequalities using 'or', it doesn't have to be both. Our solution, therefore looks like this:
