Can you please clarify what you want to ask? Thanks!
Answer:
b = -125/9
Step-by-step explanation:
1 + log5 ( -9b) = 4
Subtract 1 from each side
1 -1+ log5 ( -9b) = 4-1
log5 ( -9b) = 3
Raise each side to the base 5
5^ log5 ( -9b) = 5^3
This will cancel the log5
-9b = 125
Divide each side by 9
-9b/-9 = 125/-9
b = -125/9
Answer: [-1,infinity)
Step-by-step explanation:
Answer:
6/8 or 3/4
Step-by-step explanation:
Because the denominator is the same, just add all the numerators, 1+2=3, then 3+3=6. So 6/8 or when simplified, 3/4.
I believe 15 would be the correct answer
