Pretty sure it’s 148.10% because ofc it’s 100% and then 468-152=152 . Then 152 is 48.10 % of 316 so add that to the 100%
Answer:
theres nothing
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
Given the logarithmic equation
![\log_4x+\log_4(x-3)=\log_4(-7x+21)](https://tex.z-dn.net/?f=%5Clog_4x%2B%5Clog_4%28x-3%29%3D%5Clog_4%28-7x%2B21%29)
First, notice that
![x>0\\ \\x-3>0\Rightarrow x>3\\ \\-7x+21>0\Rightarrow 7x](https://tex.z-dn.net/?f=x%3E0%5C%5C%20%5C%5Cx-3%3E0%5CRightarrow%20x%3E3%5C%5C%20%5C%5C-7x%2B21%3E0%5CRightarrow%207x%3C21%5C%20x%3C3)
So, there is no possible solutions, all possible solutions will be extraneous.
Solve the equation:
![\log_4x+\log_4(x-3)=\log_4x(x-3),](https://tex.z-dn.net/?f=%5Clog_4x%2B%5Clog_4%28x-3%29%3D%5Clog_4x%28x-3%29%2C)
then
![\log_4x(x-3)=\log_4(-7x+21)\\ \\x(x-3)=-7x+21\\ \\x^2-3x+7x-21=0\\ \\x^2+4x-21=0\\ \\D=4^2-4\cdot 1\cdot (-21)=16+84=100\\ \\x_{1,2}=\dfrac{-4\pm 10}{2}=-7,\ 3](https://tex.z-dn.net/?f=%5Clog_4x%28x-3%29%3D%5Clog_4%28-7x%2B21%29%5C%5C%20%5C%5Cx%28x-3%29%3D-7x%2B21%5C%5C%20%5C%5Cx%5E2-3x%2B7x-21%3D0%5C%5C%20%5C%5Cx%5E2%2B4x-21%3D0%5C%5C%20%5C%5CD%3D4%5E2-4%5Ccdot%201%5Ccdot%20%28-21%29%3D16%2B84%3D100%5C%5C%20%5C%5Cx_%7B1%2C2%7D%3D%5Cdfrac%7B-4%5Cpm%2010%7D%7B2%7D%3D-7%2C%5C%203)
Hence,
and
are extraneous solutions
