Answer 1

Answer:

I) n >=3

solution set ={3,4,...so on}

2)x >= -51

solution set={}

3)-3<=x<=6

sol set={-3,-2,-1,0,1,2,3,4,5,6}

Hope this helps

Answer 2

Answer:

solved

Step-by-step explanation:

i) 4n+7≥3n+10

n≥3

n = { 3,4,5 ...}

ii) 6(x+6) ≥ 5(x-3)

6x+36 ≥ 5x - 15

x ≥ - 51

n = { -51, -50 , -49 , ...}

iii) -13 ≤ 5x + 2 ≤ 32

subtract 9.5

-22.5 ≤ 5x -7.5 ≤ 22.5

║5x-7.5║ ≤ 22.5

║5x ║ ≤ 30

║x║ ≤ 6

x = { ....., -1 ,0,1,2,3,4,5,6}
