What is the answer meyn?

Answer:

the best value is two 50 ml bottles

Step-by-step explanation:

Okay focus with me , if you buy a bottle of 50 ml you will get a second for half price so we can say that --> 2 bottles of 50 ml =

$45 + \frac{45}{2} = 67.5$

We get 100 ml with £67.5 just , but when you buy 80ml you must pay £55 Hum !

then you can dived the volume of bottle with price ...

the price of one ml is 0.675 in first State

$\frac{67.5}{100 } = 0.675$

in the second state the price of one ml is

$\frac{55}{80} = 0.6875$

then :

$0.675 < 0.6875$

so the best value is two 50 ml bottles

F(x)=-3/4x+9 what are the steps for finding f^-1(x)

ozzi

The inverse function $f^{-1}(x)$ is such that

$f\left(f^{-1}(x)\right) = x$

If $f(x)=-\frac34x+9$ , then we have

$f\left(f^{-1}(x)\right) = -\dfrac34f^{-1}(x)+9 = x$

Solve for the inverse :

$-\dfrac34f^{-1}(x)+9 = x \\\\ -\dfrac34f^{-1}(x) = x-9 \\\\ f^{-1}(x) = -\dfrac43(x-9) \\\\ \boxed{f^{-1}(x) = -\dfrac43x+12}$
