e)-3x+9>0
f) 3x-8<0
g)-2x-4≥0
h)7x-14≤0
se puderem me ajudar ficarei grato!!

Answer 1

a) x-2<0

x < 0 + 2

x < 2

b4x-12>0

4x > 12

x > 12/4

x > 3

c)-x+3<0

- x < - 3 (-1)

x > 3

d)5x-1>0

5x > 1

x> 1/5

e)-3x+9>0

- 3x > - 9

x > -9/-3

x< 3

f) 3x-8<0

3x < 8

x< 8/3

g)-2x-4≥0

- 2x ≥ 4(-1)

2x ≤ - 4

x ≤ -4/2

x≤ - 2

h)7x-14≤0

7x ≤ 14

x≤ 14/7

x≤ 2
