If y varies inversely as x and y=3 when x=14, find x when y=6

1 answer:

3 0

X=7 What you can do is look at the first two values given, and make them x1 and y1. Then your next value here is y2.

So x1 is 14, and y1 is 3. y2 becomes 6. X2 is unknown.

Then make the formula: x1/y2 is equal to x2/y1
(You are setting two fractions equal to each other)

That makes 14/6=X/3. When we cross multiply, we find that x=7.

Which value of n makes the following equation true?

grin007 [14]

Answer: d. 512

Step-by-step explanation:

You need to remember that:

$(\sqrt[3]{x})^3=x$

Then, given the equation:

$\sqrt[3]{n}=8$

You can find the value of "n" that make the equation true, by solving for "n".

So, to solve for "n", you need to raise both side of the equation to power 3. Therefore, you get:

$\sqrt[3]{n}=8$

$(\sqrt[3]{n})^3=(8)^3$

$n=512$

Then, the value of "n" that makes the equation $\sqrt[3]{n}=8$ true is: 512 (You can observe that this matches with the option d).
