60 POINTS Explain the process and solve a logarithmic equation. log x + log 8 – 2log 4 = 7.

Step-by-step explanation:

Recall the power property of logarithms which states:

to re-write

and then use the product and quotient rules of logarithms:

and

to rewrite the combination of logarithms on the left of the equal sign as a single logarithm:

and now re-write this equation in exponent form to get rid of the logarithm:

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
