jesse bought a car for 2,200,000 he sold for a 20% profit from the money raised from the sale he bought another more expensive c
olya-2409 [2.1K]

Answer:1,76,000 Profit

Step-by-step explanation:

Given

Jesse initially bought the car for 2,200,000 and sold it for 20 %

S.P.=C.P.(1+Profit%)

so, the Selling price of the car is S.P.=2,200,000\times 1.2=2,640,000

profit=2,640,000-2,200,000=4,40,000

After this, he bought another car and sells it for a 10 % loss

So, the selling price of the car is 2,640,000\times 0.9=2,376,000

loss=2,640,000-2,376,000=2,64,000

Net Profit or loss=4,40,000-2,64,000=1,76,000 Profit

Step-by-step explanation:

The computation of the number of hours will the battery last is given below:

Given that

The capacity of her battery is 2 by 5

And, it declines 1 by 9 for every hour

So,

= \frac{2}{5}\times \frac{9}{1}\\\\= \frac{18}{5}\\\\= 3\frac{3}{5}

= 3.6 hours

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}
