Question

1. −2x ≤ 6 2. x−3 ≥ 2 3. x 2 > 3 4. − x 3 > 1 5. −2x ≤ −6 6. − x 2 < 3 7. −2x ≥ 6 8. x+5 > 3 9. x−5 > 2 10. x+1 ≥ 3 11. 2x < −4 12. −2x ≥ −4 13. x−5 ≥ 3 14. x 2 < −3

I need to answers to all of these! Thank you!!

Answer 1

Answer:

We have,

5(2x−7)−3(2x+3)≤0

⇒10x−35−6x−9≤0

⇒4x−44≤0⇒x≤11

And 2x+19≤6x+47

⇒2x−6x≤47−19

⇒−4x≤28⇒x≥−7

Thus using above two we have −7≤x≤11
