For this case, we must find the inverse of the following function:

We follow the steps below:
We exchange the variables:

We put the variable y on the left side of the equation:

We apply logarithm properties:

So:

Answer:

Option B
Answer:
A reasonable estimate for the solution is the point (1.1,-1.9)
Step-by-step explanation:
we have
-----> equation A
----> equation B
Solve the system by graphing
Remember that the solution of the system of equations is the interection point both graphs
using a graphing tool
The solution is the point (1.091,-1.818)
see the attached figure
therefore
A reasonable estimate for the solution is the point (1.1,-1.9)
You have to round it to the nearest hundreds
2x + 6 = 5
5x – 9 = 8x – 4
5x = 2y – 8
6b + 4 = 2
6 + 4 = 10
