It's a function of function f(g(x))

f(x) = (x-3)/x  and g(x) =5x-4

Just plug the value (5x-4) in x of f(x)

f(x) = [(5x-4) -3] / (5x-4) ==== f(x) = (5x-7)/(5x-4)


The domain are all the value of x different from 4/5 (or the number that render the denominator nil.

In short 5x-4 ≠ 0 or x≠ 4/5

Domain ={x/x ≠5/4}

snow_lady [41]

Answer:

900

Step-by-step explanation:

To get your answer, you can just multiply 20 seconds by 3 to get 60 seconds, which is a minute.

Since whatever you do on one side you have to do to the other, multiply 300 mi by 3 as well. That would get you 900.

Which of the following fractions can be represented by a terminating decimal?
Karo-lina-s [1.5K]

Answer:

B) 13/8

Step-by-step explanation:

First we need to understand what a terminating decimal is: It is a decimal that has a finite number of decimal values that are not zero, meaning that its decimal values end at some point

Let's go through our possible answers with trial and error:

A) 8/9

8/9 = 0.888888888888...9 (Incorrect)

B) 13/8

13/8 = 1.625 (Correct)

C) 4/3

4/3 = 1.3333333333...4 (Incorrect)

D) 6/11

6/11 = 0.545454545454...54 (Incorrect

13/8 is our answer because in decimal form it is a terminating decimal.
