If y is inversely proportional to x, and if y = 15 when x = 23 then 15/1 = k/23^3 = 15/1 = k/12167, y ∝ x−1 = 15 ∝ k/12167
<h3>How do we express this in inverse proportion?</h3>
Given, y is inversely proportional to x
or
y ∝ x−1
this is if and only if y ∝ 1/x
y = 1/xk
Also, we know that if y = 15 when x = 23^3
then 15/1 = k/23^3
⇔
multiply both sides by 23
345 = k this is our constant of proportionality
⇒
this gives us our formula
y = 345/x
Then consider when y = 15
then
15 = 345/x
⇔
multiply both sides by x
15x = 345
⇔
divide both sides by 15
x = 23
Therefore, the correct answer is as given above

Chairman Mao had to overcome the Ruler before that. He also had to destroy everything that would be "four olds" meaning he had to destroy old ideas, old culture, old thoughts.

Gold and jobs i guess there are a lot but those are what i thought of
Because it is a sensitive topic. Some believe that it was revenge for Japan's bombing of Pearl Harbor, while others say it was wrong to use such powerful weapons, bombing not one, but two towns, and killing more than 129,000 innocent japanese people.

Also, he was Jamaican, not African American. That already eliminates 2 options.
