Question

Solve the compound inequality 6b < 42 or 4b + 12 > 8. (1 point)

b < 6 or b > 5
b < 7 or b > -1
b < 7 or b > 1
b > 6 or b < 5

Answer 1

So we have

6b < 42

divide both sides by 6 here to solve for 'b'

6b < 42
---------
6 6

b < 7

And then we have

4b + 12 > 8

Subtract both sides by 12

4b > -4

divide both sides by 4

4b > -4
--------
4 4

b > -1

So the solution would be

b > -1 or b < 7

Answer 2

So the second one!?
