Answer:

f⁻¹(y) = y^(-7/17)

Step-by-step explanation:

f(x) = x^(-17/7)

To find the inverse, switch x and y, and solve for y.

x = y^(-17/7)

x^(-7/17) = y

Therefore, f⁻¹(y) = y^(-7/17).

Franco is reading a book with 482 pages he reads 30 pages each night. how many pages will he read in 7 nights? show your work
Sergeu [11.5K]
The number of pages in the book is actually irrelevant.

Franco reads 30 pages in 1 night. To find how many pages he reads in 7 nights, just multiply by 7.

30*7=210

Franco reads 210 pages in 7 nights.


Solving with Equivalent Ratios:

The ratio of pages he reads per night is 30:1. We need to figure out the ratio <em>x</em>:7, where the variable <em>x</em> is the number of pages he reads in 7 nights.

30:1=<em>x</em>:7

To find x we need to see the similarity between both ratios. This is found by dividing two of the equal sides, here it would be 7 and 1.

7/1=7

This means that the second ratio is 7 times the first ration. To find <em>x</em>, just multiply 30 by 7.

30*7=210

Franco reads 210 pages every 7 nights.
