Question

Which are correct representations of the inequality 6x ≥ 3 + 4(2x – 1)? Check all that apply.

Answer 1

Answer:

6x ≥ 3 + 4(2x - 1)

⇔ 6x ≥ 3 + 8x - 4        => remove the parentheses

⇔ 6x - 8x ≥ 3 - 4

⇔ -2x ≥ -1

⇔ 2x ≤ 1 (or 1 ≥ 2x)

⇔ x ≤ 1/2

⇔ x ≤ 0.5

The answer for the question should be:

1 ≥ 2x

6x ≥ 3 + 8x – 4

and the first graph.

Answer 2

Answer:

1 ≥ 2x

6x  ≥ 3 + 8x - 4

and the first line graph.

Step-by-step explanation:

6x ≥ 3 + 4(2x – 1)

6x  ≥ 3 + 8x - 4

6x -  8x ≥  -1

-2x   ≥ -1

x  ≤ 1/2

or 1 ≥ 2x.
