Hey there!

10 to the fifth power is equivalent to the expression:

10 x 10 x 10 x 10 x 10 because you are multiplying 10 by 10 5 times.

Hope this helps you.
Have a great day!

I think you meant this: (3m/m-6)*(5m^3-30m^2/5m^2)
If that's the case, the simplified form:

25 kids in all
2xboys:3x girls

so the equation would be
2x+3x=25
solve,
5x=25
/5 /5
x=5
2x=10
3x=15

-y varies inversely with x. When y = 9.6, x = 12. What is the value of k, the constant of inverse variation?

alisha [4.7K]

Question 1:

For this case we have an equation of the form:

$y = \frac {k} {x}$

Where,

k: inverse variation constant.

Then, substituting values we have:

$y =\frac {k} {x}$

From here, we clear the value of k.

We have then:

$k = 9.6 * 12\\k = 115.2$

Answer:

the constant of inverse variation is:

$k = 115.2$

Question 2:

For this case we have:

$y = \frac {k} {x}$

Where,

k: constant of variation.

Then, substituting the value of the constant we have:

$y =\frac {5.6} {x}$

We now substitute the value of x:

$y = \frac {5.6} {4}\\y = 1.4$

Answer:

the value of y when x = 4 is: $y = 1.4$
