Question

Solve the compound inequality 6b < 24 or 4b + 12 > 4.

Answer 1

for 6b<24, what would you do?

Answer 2

you have to isolate "b" for that you need to think what you should add or remove to make "b" alone.

Answer 3

b< 4 or 4b>-8
b>-2


b<4 or b>-2

Answer 4

is that right?

Answer 5

they need to be combined however, so it basically is just rewriting what you got with one b.
4>b>-2

Answer 6

thanks (:

Answer 7

6b < 24
b < 24/6
b < 4

4b + 12 > 4
4b > 4 - 12
4b > -8
b > -2

-2 < b < 4
