Question

resolva as inequações

a) 22x>3
b)x+1>-1
c)2(3x+1)<4(5-2x)
d) a/2 < 7
e) 3Z-1/2>1/4
​

Answer 1

Resposta:

a) 3/22

b) -2

c) 9/7

d) 14

e) 1/4

Explicação passo-a-passo:

a) x> 3/22

b) x+1>-1

x> -1 -1

x> -2

c) 2(3x +1) < 4(5-2x)

6x +2 < 20 - 8x

6x + 8x < 20 -2

14x < 18

x< 18/14< 9/7

d) a/2 < 7

a/2 < 7/1 (mmc= 2)

1.a < 2.7

a < 14

e) 3z -1/2> 1/4

3z/1 - 1/2 > 1/4 (mmc= 4)

4. (3z) - 1.2 > 1.1

12z -2 > 1

12z > +2+1

12z > 3

z> 3/12> 1/4
