The value of an antique plate after x years can be modeled by f(x) = 18(1.05)x. Which graph can be used to approximate the numbe
r of years it will take for the plate’s value to be $30?
2 answers:
Answer:
The approximate number of years is 10
The graph in the attached figure
Step-by-step explanation:
Let
f(x) the value of an antique plate
x is the number of yeras
we know that
The system of equations that represented the problem is equal to
----> equation A
----> equation B
Solve the system by graphing
The solution of the system of equations is the intersection point both graphs
using a graphing tool
The solution is the point (10.47,30)
see the attached figure
therefore
The approximate number of years is 10
