How would you simplify (log 27/logx) x (log x^2/log3)? I don’t think I did this correctly.
Kaylis [27]

Answer:

6

Step-by-step explanation:

logx 27  * log3 x^2

The first step is to convert to base 10

(log 27/logx) * (log x^2/log3)

27 = 3^3 so we can rewrite this

(log 3^3/logx) * (log x^2/log3)

log a^b  = b log a

(3 log 3/logx) * (2log x/log3)

We can cancel the log x in the numerator and denominator and the log 3 in the numerator and denominator

3 * 2

What is the equation of the line written in general form? -3x - y + 2 = 0 3x - y - 2 = 0 3x + y - 2 = 0
nlexa [21]

Answer:

3x + y - 2 = 0

Step-by-step explanation:

The equation of a line in general form is

Ax + By + C = 0 ( A is a positive integer and B, C are integers )

Given

- 3x - y + 2 = 0 ← multiply through by - 1

3x + y - 2 = 0 ← in general form

Rectangle is 2/5 in. long and 1/3 in. wide.
VARVARA [1.3K]
Answer:  "<span>\frac{2}{15}   in²</span> " . {that is:  " (2/15) in² . "}. 
___________________________________________
Explanation:
___________________________________________
The formula/equation for the Area of a rectangle:  

A = L * w  ;  

       in which:   L  =  <span>⅖ in ; 
</span>                       w =  ⅓ in;
___________________________
Find the area;  in a "fraction value" ;
_______________________________
   A = L * w    ;  
 
          →  Substitute the given values for "L" (length) and "w" (width);
       and solve for "A" (area) in the "form of a fraction:
__________________________________________________

A   = (2/15) in  *  (1/3)  in ;
 
→ A    = [(2*1) / (5*3)] *  in * in ; 
______________________________________________________
→  Answer:  The area is:  " \frac{2}{15}   in² " .
                                          
                                             {that is, "(2/15) in² " .}.

Y= x + 6<br>y= -x+2<br><br>solve each system of equations by substitution
ser-zykov [4K]

Answer:

x= -2
y=4

Step-by-step explanation:


Since we have an equation set equal to y, we can plug it in for either value of y.

I will be using y= x+6 in this case.

Plug in x+6 for the other equation, so instead of y=-x+2 it will now be that x+6 = -x+2

Now add x to both sides, and that will remove the x on the left side leaving us with 2x+6 = 2

Now, subtract 6 from both sides to get 2x isolated, and you will get 2x= -4

Divide both sides by 2 to get x= -2

Not plug x= -2 in back for the top (or bottom) equation and get that y=4

Hope this helps and isn't too complicated!
