An Ivy League college accepts 5 students for every 100 that apply. What fraction of applicants is accepted? Write your results i
Law Incorporation [45]

Hello there!

To find the fraction of applicants that are accepted into the Ivy League college, all you have to do is put the number of students accepted (numerator) over the total number of students that apply (denominator). This makes the fraction 5/100. This fraction can be simplified. To simplified, find the GCF of the two numbers. The GCF of 5 and 100 is 5. Divide both parts by 5. 5/100 ÷ 5/5 is 1/20. There. 5/100 is 1/20 in simplest form. The Ivy League college accepts 1/20 of it's applicants.

Which function is the inverse of f Superscript negative 1 Baseline (x) = negative one-fifth x minus four-fifths?
DedPeter [7]

Answer:

f(x) = -5x - 4

Step-by-step explanation:

We want to get the inverse of the following function:

f^-1(x) = (-1/5)x - 4/5

To do that, we have to replace x with f(x) and f^-1(x) with x, as follows:

x = (-1/5)f(x) - 4/5

And then solve for f(x), the inverse of f^-1(x).

x + 4/5 = (-1/5)f(x)

f(x) = -5x + (-5)4/5

f(x) = -5x - 4

To check our result we compute a pair (x, f(x))

x   f(x)

1   -5*1 - 4 = -9

which has to be equivalent to (-9, 1) in the original function

x      f^-1(x)

-9     (-1/5)*(-9) - 4/5 = 1
