Question

Which of the following is a solution of the compound inequality?
3x + 8 < 2 or x + 12 > 2 - x

x < -2 or x > 5
x < -6 and x > 5
All real numbers
No solution

is it the first one?

Answer 1

Solve each side. Start with the left side:
3x + 8 < 2
What's the next step?

Answer 2

subtract 8 from each side

Answer 3

I thought EmmaH asked the question.

Answer 4

i got x>-2 and x>-10-x so i figures it was the first one...

Answer 5

Do the second part again.
x + 12 > 2 - x

Answer 6

Add x to both sides
2x + 12 > 2
Subtract 12 from both sides
2x > -10
x > -5

Answer 7

ok so it is the first one:)

Answer 8

The solution to both sides is x < -2 or x > -5
Try plotting that on a number line.

Answer 9

The first one has x > 5. We get x > -5, so it's not the first one.

Answer 10
