Find the inverse of the rational function <br> F(x)= 2x/x+3, x≠-3
timama [110]

as you already know, to get the inverse of any expression we start off by doing a quick switcheroo on the variables and then solving for "y", let's do so.

\stackrel{f(x)}{y}~~ = ~~\cfrac{2x}{x+3}\implies \stackrel{\textit{quick switcheroo}}{x~~ = ~~\cfrac{2y}{y+3}}\implies xy+3x=2y\implies xy-2y+3x=0 \\\\\\ xy-2y=-3x\implies \stackrel{\textit{common factoring}}{y(x-2)=-3x}\implies y=\cfrac{-3x}{x-2}\implies \stackrel{f^{-1}(x)}{y}=\cfrac{3x}{2-x}

What is the answer for this one?
pshichka [43]
<h2>1. Find the SA of all of the parts:</h2>

SA of Triangle parts:

We won't be doing 5x6x1/2 because if we want the surface area of 2 areas, then we will just do normal (5x6)

(2 × 8 2) + (3 × 10 2)

SA: B x H

    : 5 x 6

    : 30

The surface area of the triangular parts is 30cm²

SA of Large Rectangular (in the middle) part:

SA: L x W

    : 6 x 16

    : 96

The surface area of the rectangular parts is 96cm²

SA of Large Rectangular (top&bottom) part:

SA: L x W x 2

    : 16 x 8 x 2

    : 256

The surface area of the rectangular parts is 256cm²

<h2>2. Add all the SA's to get FINAL answer:</h2>

30+96+256=382

<h2>So hence, The SA of the Triangular prism is: 382cm²</h2>

A soccer field has a perimeter of 326 metres. Its area is 6370 square metres. What are the dimensions of the field?
Burka [1]

Answer:

Step-by-step explanation:

chiều dài:x,x>0

chiều   rộ:y

\left \{ {({x+y)*2=326} \atop {xy=6370}} \right.

\left \{ {{x+y=163} \atop {xy=6370}} \right.

\left \{ {{y=163-x} \atop {xy=6370}} \right.

\left \{ {{y=163-x} \atop {x*(163-x)=6370}} \right.

\left \{ {{y=163-x} \atop {163x-x^{2} =6370}} \right. \\

\left \{ {{y=163-x} \atop {x_{1} =98; x_{2} =65}} \right.

\left \{ {{y=65} \atop {x=98}} \right.
