Okay, i don't want to give you the direct answer because i want you to know how to do it ... First you multuply $4.30 x .4 and you will get a number... remember that number in your head and subtract it from the original amount of $4.30... then once you get the number from subtracting the discount, multiply that number by .6..... then with that number, add the sales tax and there is your answer!

Find the inverse of A(x) = x^1/5+5

antiseptic1488 [7]

In order to find the inverse of

$A(x)=x^{\frac{1}{5}}+5$

we first replace A(x) with y:

$y=x^{\frac{1}{5}}+5$

Then we replace every y with an x and every x with a y, like so:

$x=y^{\frac{1}{5}}+5$

We solve this new equation for y:

$x-5=y^{\frac{1}{5}}\Rightarrow y^{\frac{1}{5}}=x-5$

We raise both sides of the equation to the fifth power:

$(y^{\frac{1}{5}})^5=(x-5)^5$ $y=(x-5)^5$

Finally, we replace y with the inverse of the function:

$A^{-1}(x)=(x-5)^5$

and that is the inverse function.

Find the slope of the given line, if it is defined.

4vir4ik [10]

Answer:

The slope equals -⁴/3

Step-by-step explanation:

Slope of the line passing through the origin (0, 0) and (-9, 12):

Slope = $\frac{y_2 - y_1}{x_2 - x_1} = \frac{12 - 0}{-9 - 0} = \frac{12}{-9} = -\frac{4}{3}$

Slope (m) = -⁴/3
