Question

Help me answer these 4 questions please! ( one step inequalities )

1) e +3≥9

2) 21≥7i

3) i-13≥4

4) -8≥i(-2)

( I need actual answers not if they are true or false! )

Answer 1

Explanation:

1) e +3 ≥ 9

(e + 3) + (- 9) ≥ 9 + (- 9)

e + 3 - 9 ≥ 9 - 9

e ≥ 6

2) 21 ≥ 7i

7i ≤ 21

`i` E ( -
`_( \infty)` 3]

3) i - 13≥ 4

(i - 13) + 13 ≥ 4 + 13

`i` E( 17,
`{ \infty}`)

4) -8 ≥ i(-2)

-8 ≥ -i · 2

-8 ≥ -2i

`i` E [4, infinite) (No solution)
