Answer:
y = 7x - 33
Step-by-step explanation:
Using a given point and slope, we need to use point-slope form.
m= 7 (slope)
= 3 (x value from given point)
= -12 (y value from given point)
Now we Substitute values in
Double negative with - (-12) makes 12 positive
Use distributive property for 7(x -3)
Subtract 12 from both sides
The extraneous solution of the logarithmic problem is -4.
A log function is a way to find how much a number must be raised in order to get the desired number.
can be written as
where a is the base to which the power is to be raised,
b is the desired number that we want when power is to be raised,
c is the power that must be raised to a to get b.
Solving the function using the basic logarithmic value, we get,
If we solve further we will get that the value of x can be either -4 or 4, if take the value of x as -4, in the beginning then you will get log₃(18(-4)³) as the log of negative value which is impossible.
Hence, x=-4 is an extraneous solution.
