Answer:

1/3

Step-by-step explanation:

Multiplicative inverse means we want to end up with 1

3 * what = 1

Divide each side by 3

3* what /3 = 1/3

what = 1/3

The multiplicative inverse of 3 is 1/3

(2+x)dy/dx=3y need help

den301095 [7]

$(2+x) \frac{dy}{dx} =3y$
$\frac{1}{3y} dy= \frac{1}{2+x} dx$
$\int { \frac{1}{3y} } \, dy = \int { \frac{1}{2+x} } \, dx$
$\frac{1}{3}\ln(3y) = \ln(2+x) + C$
(raise both to the power e): $e^{ \frac{1}{3}\ln(3y)}=e^{\ln(k(2+x))}$
$(3y)^ \frac{1}{3} =k(2+x)$
$3y=k(2+x)^3$
$y= k(2+x)^3$

Which function below is the inverse of f(x) = x2 − 25?

Viktor [21]

$f(x) = x^{2} - 25$
Let f(x) = y
thus y = $x^{2} - 25$
switch the position of y and x in the equation
$x = y ^{2} - 25$
then solve for y in this case
$x + 25 = y^{2} 
$
∴ y= $\sqrt{x + 25}$

Thus, $f^{-1} (x) = \sqrt{x + 25}$
