Question

Inequalities help?

1. x – 3 > –9

2. –2x + 1 ≤ –11

3. 10 < –3x + 1

4. 2(x + 5) > 8x – 8

5. –2(x – 3) ≥ 5 – (x + 3)

Answer 1

1. you have to add 3 to both sides to get x alone. and -9+3 is -6 so it's x>-6

Answer 2

Okay, so for number two,
If I subtracted one from both sides,
it would be -2x < -12?

Answer 3

I'm trying to apply the same terms.

Answer 4

Thank you, this is what I needed.

Answer 5

2. You have to subtract 1 from the -11. So you'd get -2x≥-12 (since you are now dividing by a negative my teacher told us to switch the sign around) You divide by -2 and get x≥6
