Answer:
−3a+38
Step-by-step explanation:
i simplified the expression
The answer is B because it’s not a straight line and x can not have an exponent of 2 bc it will make it nonlinear
Answer:
3 hour and 30 minutes
Step-by-step explanation:
Divide
I believe you mean and rather than in. If that is the case then:
55:11
Which simplifies to:
5:1
Answer:
lnx/ln4
Step-by-step explanation:
Given
y=4^x
In order to find the inverse of the function the first step is to replace the y with x and x with y
So,
Replacing x with y and y with x
x= 4^y
We have to find the value of y explicitly to find the invers.
The above equation can also be written as:
4^y=x
As the variable is in exponent, to bring it down, ln has to be taken on both sides.
ln 4^y =ln x
The power of will be multiplied with the ln.
y ln4=lnx
y=lnx/ln4
So,
The inverse is lnx/ln4 ..
