ANSWER
EXPLANATION
The given geometric sequence is
400, 200, 100...
The first term is
The common ratio is
The nth term is
We substitute the known values to get;
The slope is -3/2. It’s negative because if you see the line, it’s going down. Therefore the slope is negative. And how you get this number? Just pick a point and another point and do rise over run. And you go 3 down and 2 across because it’s negative. If it was positive it will be 3/2. Which will mean 3 up 2 across.

Answer:
1.59
Step-by-step explanation:
log (2x-3)= log (3-x) -2
log (2x-3)/(3-x) =-2
If we remove log,
2x-3/(3-x) = e^-2
2x-3= 3e^-2 -xe^-2
2x+ xe^-2 = 3e^-2+3
x(2+e^-2) = 3( e^-2+1)
If you use calculator you will get answer nearly equal to 1.59.
