SOLUTION
From the question, we are told that y varies inversely as x
This is mathematically written as

Now, we will remove the proportionality sign and replace it with equal to sign =
If we do this, we will intoduce a constant k

So we have the formula

We will substitute the values of x for 10 and y for 8 into the formula to get k, we have

Now, we will substitute k for 80 back into the formula to get the inverse function, we have

Hence the answer is option C
Answer: " 80 inches " .

Explanation:
_______________________________
6 feet + 8 inches = ?
Note: 12 inches = 1 ft.
6 ft * (12 inches/ ft) = 72 inches;
______________________________
72 inches + 8 inches = 80 inches.

Step-by-step explanation:
The excluded values are any values of x that make the function undefined
Given

The denominator of the rational function cannot be zero as this would make it undefined. Equating the denominator to zero and solving gives the values that x cannot be.
(x + 4)(x - 2)(x - 5) = 0
Equate each factor to zero and solve for x
x + 4 = 0 ⇒ x = - 4
x - 2 = 0 ⇒ x = 2
x - 5 = 0 ⇒ x = 5
x = - 4, x = 2, x = 5 are the excluded values
Answer:
The answer is B. (4) Because a coeffecient is the number next to the letter.
