You would need to cross multiply. When you do that you get x^2-7x-8x+56. Once simplifying you get x^2-15x+56.

What is the equation, in point-slope form, for a line that goes through (2, −6) and has a slope of −34 ? plz help

Murrr4er [49]

Answer:

y = -34x + 62

Step-by-step explanation:

<u>Use the point slope form: (y - y1) = m(x - x1)</u>

<u />

(y - (-6) = -34(x - 2)

y + 6 - 6 = -34x + 68 - 6

y = -34x + 62

Answer: y = -34x + 62

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:

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