3 0

Answer:

Step-by-step explanation:

The simple answer is that logs cannot be negative and if you insert a 2 where the x is located you get a negative. Logs have to be >= 0

[text]log_5 (3x-10) = log_5 (-4)[tex]

It all has to do with logs being tied to exponents and exponents being tied to logs. Actually an inverse of an exponent is a log.

Answer:

$- 1.2 , - \frac{1}{2} ,0.44,\frac{7}{3}$

Step-by-step explanation:

We want to arrange the following numbers on the number line in order from least to greatest.

The numbers are:

$0.44, \frac{7}{3} , - 1.2, - \frac{1}{ 2}$

Let us convert everything into decimals to get:

$0.44,2. \bar3 , - 1.2, - 0.5$

Rearranging from least to greatest, we have:

$- 1.2 , - 0.5 ,0.44,2. \bar3$
