Answer:
Step-by-step explanation:
-5+8x-9=3(x+3)
8x-14=3x+9
8x-3x-14=9
5x-14=9
5x=9+14
5x=23
x=23/5
----------------------
-216-3x=-12+6x
-216-3x-6x=-12
-216-9x=-12
9x=-216-(-12)
9x=-216+12
9x=-204
x=-204/9
x=-68/3
------------------
6-213-2x=-413-x
-207-2x=-413-x
-207-2x-(-x)=-413
-207-2x+x=-413
-207-x=-413
x=-207-(-413)
x=-207+413
x=206
------------------------
-(4x+9)=2x-3(2x+3)
-4x-9=2x-6x-9
-4x-9=-4x-9
Infinitely many solutions.

Step-by-step explanation:
What matters is the base for the exponentiation to tell if its increasing or decreasing. Among positive numbers, smaller than 1 means decreasing, bigger than one means increasing. That's because for each increase of 1 in x we get another factor of the base. If it's bigger than 1 that's growth.
There are no negative bases here, but it's similar -- less than -1 (bigger in absolute value) grows, even though it oscillates back and fourth between positive and negative.
It's blurry but I see bases of 3, .6, .74, 1.3
3: growth
.6: decay
.74: decay
1.3: growth

Step-by-step explanation:
The value 0.055 is equal to 55.0 moved 3 decimal places to the left. For each decimal placed moved, divided by 10. Therefore, 0.005 as a common fraction is:
