4 0

Step-by-step explanation:

Recall that \log 10 = 1 so we can rewrite the equation above as

\log 10 + \log 2 = \log (x + 1)

Also recall that \log(ab) = \log a + \log b so the left-hand side becomes

\log [(10)(2)] = \log (x + 1)

or

20 = x + 1 \Rightarrow x = 19

How can you show that two objects are proportional with a table?
vredina [299]
So this is our table:

               -----------------
x-values | a b c d e f  |
               -----------------
y-values | g h  i  j k l   |
               -----------------

You can know that the values in the table are proportional if:

\frac{a}{g}=\frac{b}{h} =\frac{c}{i}=\frac{d}{j}=\frac{e}{k}=\frac{f}{l}

Hope that helps :)
