Answer 1

Which of the following is not a way to represent the solution of the inequality 2(x - 1) \[\le\] 10?

A)x 6

B)6 x

C)A number line with a closed circle on 6 and shading to the left.

D)A number line with a closed circle on 6 and shading to the right.

Answer 2

Well think about the question, \[2(x-1)\le 10 \rightarrow 2x-2\le10 \rightarrow 2x \le 12 \rightarrow x \le 6\] So go through each one of those possible solutions and ask yourself which doesn't fit.
When you get to the ones concerning a number line, the shaded area represents what the values of x could be.
