Step-by-step explanation:
So when we solve the inequality:
2(x - 2) >_ 2
x - 2 >_ 1 (divided 2 from both sides)
x >_ 3 (added 2 to both sides)
So with our final equation, we can work out that the answer is b, but d is also correct so I'm assuming that the inequality needs to be represented on a number line as hey usually are.
Hope this helps,
