Answer:
5 3/8
Step-by-step explanation:
3 1/8 ÷(x−4 7/28 )= 17/18 +1 5/6
Get a common denominator for the right side
3 1/8 ÷(x−4 7/28 )= 17/18 +1 15/18
Combine like terms
3 1/8 ÷(x−4 7/28 )= 1 32/18
3 1/8 ÷(x−4 7/28 )= 2 14/18
3 1/8 ÷(x−4 7/28 )= 2 7/9
We have a ÷ b = c
Rewriting as a ÷c = b
3 1/8 ÷ 2 7/9 = (x−4 7/28 )
Changing from mixed numbers to improper fractions
25/8 ÷ 25 /9 = (x−4 7/28 )
Copy dot flip
25/8 * 9/25 = (x−4 7/28 )
9/8 = (x−4 7/28 )
Add 4 7/28 to each side
9/8 + 4 7/28 = (x−4 7/28 )+ 4 7/28
Simplifying the fractions
9/8 + 4 1/4 = x
Getting a common denominator
9/8 + 4 2/8 =x
4 11/8 =x
4 + 8/8+3/8 =x
5 3/8
Answer:
Yes, they are inverse functions.
Step-by-step explanation:
To determine if two functions are inverses of one another, put one in for the x in the other. If the result is f(x) = x, then they are inverses.
f(x) = ![\sqrt[3]{x-5}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx-5%7D)
f(x) = ![\sqrt[3]{(x^3 + 5)-5}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%28x%5E3%20%2B%205%29-5%7D)
f(x) = ![\sqrt[3]{x^3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%5E3%7D)
f(x) = x
So therefore, they are inverse of each other.
