Plug in for a
2(4-b)+b=1
8-2b+b=1
8-b=1
b=7
Step-by-step explanation:
Answer:
Option D.
Step-by-step explanation:
We need to find the solution to the system graphed below.
If a system of equation have 2 linear equation then the intersection point of both lines lines is the solution of the system of equations.
In the given graph two straight lines intersect each other at (-1,-1).
Point of intersection = (-1,-1)
So, by using the given graph we can conclude that the solution of given system of equations is (-1,-1).
Therefore, the correct option is D.
Answer: I don't know how to type the infinity symbol on my phone but..
(-infinity, -5)
Basically x can be anything less than -5.
Product rule:
Power rule:
The exponential function is its own derivative:
Assuming the base of 
is 
, its derivative is
But if you mean a logarithm of arbitrary base 
, we have
So we end up with
10 is greater because it equals 3.162...
