The inverse of the function f(x) = 2x - 10 is f-1(x) would be x/2 + 5.
Lets try to solve it,
We will be using the inverse function to solve this.
f(x) =
Replace f(x) with y.
Interchange x and y
Solve for y
Replace y with f-1(x).
Thus, the inverse of the function f(x) = 2x - 10 is f-1(x) = x/2 + 5

Step-by-step explanation:
Answer:
133.33ft/hr
Step-by-step explanation:
Between 11am and 2pm, he had 3hrs
Height change 900 - 500 = 400ft
400/3 = 133.33ft/hr
In order to convert a percent to the decimal, the number should be divided by 100 and remove the percentage sign.
<u>Step-by-step explanation:</u>
Percent stands for per hundred.
In order to convert a percent to the decimal, the number should be divided by 100 and remove the percentage sign.
Example – 75%
= 75/100
= 0.75
<u>To convert decimal to mixed fraction:</u>
1. Divide the given decimal number by the place of the decimal and remove the point from the numerator.
Example – 5.25
= 525/100
2. Simplify the fraction if possible.
Example = 525/100 = 21/4
3. Divide the numerator by the denominator.
On solving we get, 5 as the quotient and 1 as the remainder.
To convert into a mixed fraction = the remainder becomes the numerator and denominator remains the same
Mixed fraction becomes = 5 1/4
