Answer:
b = 2
Step-by-step explanation:
Original Equation:
-12 + 3b - 1 = -5 - b
Add b to both sides
-12 + 4b - 1 = -5
Add 12 to both sides
4b - 1 = 7
Add 1 to both sides
4b = 8
Divide both sides by 4
b = 2
Hope this is what you need :)
Answer:
Option B - 
Step-by-step explanation:
Given : Fidel has a rare coin worth $550. Each decade, the coin's value increases by 10%.
To find : Which expression gives the coin's value, 6 decades from now?
Solution :
The given situation represents the exponential function,

where, a is the initial value i.e. a=$550
r is the increased rate r=10%
n is the time i.e. n=6
Substitute the value in the formula,


Therefore, option B is correct.
