Assume that y varies directly as x then solve. If x = 12 <br> when y = 15 find x when y = 21.

Viefleur [7K]

Answer:

Step-by-step explanation:

12 and 15 are both dividable by 3 and 3 apart so if you subtract 21 by 3 than you get 18

If point C is not located between points A and B, then AC + CB= AB

Naddik [55]

The location AC + CB is mathematically given as

AC + CB= AB

This is further explained below.

<h3>What is the location AC + CB of AB ?</h3>

Because point C can be seen to be in between A and point B, the equation AC + CB must equal AB.

It is important to keep in mind that point C may be located in any part of the space between A and B; yet, the solution will still be considered to be AB in this scenario.

Again, AC + CB = AB.

In conclusion, By way of deduction: if point C is located between points A and B, then it follows that point C is situated on line AB conversely, if point C is not situated on line AB, then it cannot be located between points A and B. As a result, you are able to deduce that AB is a line and that point C is situated on it in the middle of points A and B.
