Question

Which of the following is not a way to represent the solution of the inequality 2(x − 1) greater than or equal to −12?

Answer 1

Let us solve the inequality first

$2(x-1)\ge -12$

Dividing through by 2 gives

$(x-1)\ge -6$

Grouping like terms gives

$x\ge -6+1$

This implies that;

$x\ge -5$

This corresponds to option A in words

If we rewrite as

$-5\le x$

it will correspond to option C in words

Representing on diagram corresponds to option D (See attachment)

All are correct ways to represent the solution except B.

The correct answer is option B
