Find the derivative of 3e^y+x=y

Sindrei [870]

You have the following function:

$y=3e^y+x$

Derivate implictly the previous expression, as follow:

$y^{\prime}=3e^yy^{\prime}+1$

Where you have used that:

$(e^y)^{\prime}=e^yy^{\prime}$

Then, the implicit derivative of the given expression is:

$y^{\prime}=3e^yy^{\prime}+1$

Next, solve for y' as follow:

$\begin{gathered} y^{\prime}-3e^yy^{\prime}=1 \\ (1-3e^y)y^{\prime}=1 \\ y^{\prime}=\frac{1}{1-3e^y} \end{gathered}$

The pair of points is on the graph of an inverse variation. find the missing value. (5,4) and (x,7)

d1i1m1o1n [39]

One form of the relation of inverse variation is y = k/x.

first step: Find the value of k: Taking the values x=5 and y = 4, 4=k/5, or k=20. Then, y = 20/x.

Next: Let y = 7 and find the corresp. value of x: 7=20/x, or 7x=20, or

x = 20/7 (answer)

Chelsea has four hours of free time on Saturday. She would like to spend no more than 2/3 of an hour on each activity. How many

Galina-37 [17]

Namely, how many times 2/3 goes into 4, well, let's just divide them then

$\bf \cfrac{\stackrel{\textit{total hours}}{4}}{\stackrel{\textit{hours per activity}}{\frac{2}{3}}}\implies \cfrac{\quad \frac{4}{1}\quad }{\frac{2}{3}}\implies \cfrac{4}{1}\cdot \cfrac{3}{2}\implies \cfrac{12}{2}\implies 6$
