That's great!

Maybe you should use that to help others, in person, on video call, in a group, your family, or even on Brainly!

Show work please for number 2
Pavlova-9 [17]

The combined distance between CD and DE is CE, so...

2x+4 + 6 = x+14   Simplify like terms..

2x + 10 = x + 14      Subtract x from both sides..

x + 10 = 14    Subtract 10 from both sides...

<h2><u><em>x = 4</em></u></h2>

Proof: 2 (4) + 4 + 6 = 4 + 14

       8 + 10 = 18

Find the local extreme values of the function f(x, y) = xy - x2 - y2 - 3x - 3y + 12
aev [14]
f(x,y)=xy-x^2-y^2-3x-3y+12

First compute the first-order partial derivatives and find the critical points.


f_x=y-2x-3
f_y=x-2y-3

Both first order derivatives vanish at (x,y)=(-3,-3).


Computing the Hessian, we get

\mathbf H(x,y)=\begin{bmatrix}f_{xx}&f_{xy}\\f_{yx}&f_{yy}\end{bmatrix}=\begin{bmatrix}-2&1\\1&-2\end{bmatrix}

We have \det\mathbf H(x,y)=3>0, which means (-3,-3) is an extremum of f(x,y). Since f_{xx}(-3,-3)=-2, this extremum is a local maximum of f(x,y) with a value of 21.
