Answer:
![f(x)=log_ex](https://tex.z-dn.net/?f=f%28x%29%3Dlog_ex)
Step-by-step explanation:
By definition, we can write ln instead of log. WHEN??
Whenever the base of the logarithm is the number "e".
Hence, when we have:
![Log_e](https://tex.z-dn.net/?f=Log_e)
We can write it in shortcut as:
![Log_e=ln](https://tex.z-dn.net/?f=Log_e%3Dln)
Hence, ln x can also be written as ![Log_ex](https://tex.z-dn.net/?f=Log_ex)
Fourth answer choice is right.

Step-by-step explanation:
Answer:
7/4 + 9/-5 =
Since the denominator of the second fraction is negative the sign will change from negative to positive
We will get
7/4 - 9/5
First find the LCM
LCM of 4 and 5 is 20
7/4 - 9/5 = 5(7) - 4(9)/ 20
Simplify
We get
35 - 36/20
= -1/20
