)

d

b)

d ≤ −6

c)

d

d)

d

Answer 1

The answer is
The 4 one D
d<6

Answer 2

Option d: d ≤ 6 is the correct answer

Explanation:

Given inequality is:

`3(2d-1)\geq 4(2d-3)-3\\Expanding the terms\\6d-3 \geq 8d-12-3\\6d-3 \geq 8d-15\\Adding\ 3\ to\ both]\ sides\\6d-3+3\geq 8d-15+3\\6d\geq 8d-12\\Subtracting\ 8d\ from\ both\ sides\\6d-8d \geq 8d-12-8d\\-2d\geq -12\\Multiplying\ both\ sides\ by\ -1\\2d\leq 12\\Dividing\ both\ sides\ by\ 2\\d \leq 6`

Hence, option d: d is the correct answer ..
