Answer:
326.87
Step-by-step explanation:
First join the log4 on the left:
log4( x*(x-3) = log4(-7x+21)
Then x = -7, works: -7*(-10)=70 = -7*(-7)+21
x=-3, 18 = 42, does not work
x=3 0=0 works,
However, when one puts x = -7 in the *original* exression, log4(-7) or log4(-10) do not exist (you know why?). So x= -7 is extraneous.
Now x=3 gives log4(0) on the left and right, which does not exist.
So, C is the answer, both are extraneous. Seem to work but indeed don't work in the *original* equation
Answer: y-2=1/4(x-1)
Step-by-step explanation:
The formula for point-slope is y-y₁=m(x-x₁). Since we are given the slope m, we can fill that in. We are also given the point (x₁,y₁). We can also fill that in.
y-2=1/4(x-1)
Answer:
The approximate monthly rate of growth is 1.24%
Step-by-step explanation:
we have the future value formula
we have
----> annual interest rate
so
Find the approximate monthly rate of growth
Remember that
so
Divide the number of periods t by 12
Applying power rules property
Convert to percentage
therefore
The approximate monthly rate of growth is 1.24%
