First you subtract 3 on both side
9x=57-3
9x=54

then you divide by 9 on both sides
you got

Answer:  x = 6 .
_________________________________
<span>Explanation:
____________________________________________________
</span> Given:  9x + 3 = 57 ;  Solve for "x" ;
<span>___________________________________
  </span>Subtract "3" from EACH side of the equation:
_________________________________________
       9x + 3 − 3 = 57 <span>− 3 ;
_________________________________________
to get: 
_________________________________________
        9x  = 54 ;
__________________________________________
 Now, divide EACH side of the question by "9" ; to isolate "x" on one side of the equation; and to solve for "x" ;
____________________________________________
       9x / 9  = 54 / 9  ;
____________________________________________
          x  =  6 .

Use the product, quotient, and power rules of logarithms to rewrite the expression as a single logarithm. Assume that all variab
Viefleur [7K]

Answer:

log(x^7·y^2)

Step-by-step explanation:

The applicable rules are ...

... log(a^b) = b·log(a)

... log(ab) = log(a) +log(b)

_____

The first term, 7log(x) can be rewritten as log(x^7). Note that an exponentiation operator is needed when this is written as text.

The second term 2log(y) can be rewritten as log(y^2). These two rewrites make use of the first rule above.

Now, you have the sum ...

... log(x^7) +log(y^2)

The second rule tells you this can be rewritten as ...

... log(x^7·y^2) . . . . . seems to match the intent of the 3rd selection

a traveler has 7 pieces of luggage . how many ways can the traveler select 3 pieces of luggage for a trip
7nadin3 [17]
Well, you could assign a letter to each piece of luggage like so...

A, B, C, D, E, F, G

What you could then do is set it against a table (a configuration table to be precise) with the same letters, and repeat the process again. If the order of these pieces of luggage also has to be taken into account, you'll end up with more configurations.

My answer and workings are below...

35 arrangements without order taken into consideration, because there are 35 ways in which to select 3 objects from the 7 objects.

210 arrangements (35 x 6) when order is taken into consideration.

*There are 6 ways to configure 3 letters.

Alternative way to solve the problem...

Produce Pascal's triangle. If you want to know how many ways in which you can choose 3 objects from 7, select (7 3) in Pascal's triangle which is equal to 35. Now, there are 6 ways in which to configure 3 objects if you are concerned about order.
