0 × <span>0 = 0
0 </span>× <span>1 = 0
1 </span>× <span>1 = 1

Which means multiplication is closed under {0, 1}

</span><span>1 </span>÷ <span>1 = 1
0 </span>÷ <span>1 = 0
</span>
Division is not closed under {0, 1}

1 + 1 = 2

Addition is not closed under {0, 1}

0 - 1 = -1

Subtraction is not closed under {0, 1} either



So it's only A. Multiplication which is closed under {0, 1}

Which of the following is the correct graph of the solution to the inequality −8 greater than or equal to −5x + 2 &gt; −38? (1 p
Svetlanka [38]

The inequality should read:

-8 \geq -5x + 2 > -38

Subtract 2 from all the terms:

-10 \geq -5x > -40

Divide all the terms by -5 to get x by itself (note that you flip the inequality signs as you divide by a negative):

\boxed{2 \leq x < 8}

The inequality is 2 ≤ x < 8.

A closed dot represents ≤, and an open dot represents <. Since x can represent all values between 2 and 8, you will shade in between 2 and 8 on the number line. x is greater than or equal to 2, so there will be a closed dot on 2. x is less than 8, so there will be an open dot on 8.

The answer is 'number line with a closed dot on 2 and an open dot on 8 and shading in between'.
