Question

Calcule as desigualdades

A) (5X-3).2>(3X).2
B) 5X-3>3X
C) 5X+5≥-10X+3
D) -5X+5≤-10X+3
E) 3X+3<-7X+4

Answer 1

Explicação passo-a-passo:

Inequações Lineares:

A)

(5x - 3).2 > (3x)•2

10x - 6 > 6x

10x - 6x > 6

4x > 6

x > 6/4

x > 3/2

B)

5x - 3 > 3x

5x - 3x > 3

2x > 3

x > 3/2

C)

5x + 5 ≥ -10x + 3

5x + 10x ≥ 3 - 5

15x ≥ -2

x ≥ -2/15

D)

-5x + 5 ≤ -10x + 3

-5x + 10x ≤ 3 - 5

5x ≤ -2

x ≤ -2/5

E)

3x + 3 < -7x + 4

3x + 7x < 4 - 3

10x < 1

x < 1/10
