Answer:
d. √(1/(x+1))
Step-by-step explanation:
Just as operations can be performed on numbers and variables, so can operations be performed on functions. Here, you're asked to simplify the ratio of two functions.

At this point, you're supposed to know the factoring of the difference of squares:

Time:logs=time:logs
time/logs=time/logs
4hours:6logs=18hours:xlogs
4hours/6logs=18hours/xlogs
4/6=18/x
6/4=18/x
x=27
pick B,C,E
Answer:
A, the graph is shown
Step-by-step explanation:
Add 8.1 to both sides to find x!
hope this helps :-)
