log Subscript 3 Baseline StartFraction z squared Over 4 EndFraction
Step-by-step explanation:
The single logarithmic form f the expression is [tex]log_3(\frac{9(64z^2)}{81} )[/tex]
Logarithm and indicesGiven the logarithmic expression;
[tex]2(log_38+log_3z)-log_3(3^4-7^2)[/tex]
We are to write it as a single logarithm
Using the product and quotient law of logarithm;
[tex]2(log_38+log_3z)-log_3(3^4-7^2)\\=2(log_38+log_3z)-log_3(\frac{81}{49} )\\=2(log_38z)-log(\frac{81}{9})\\=log_364z^2-log(\frac{81}{9})[/tex]
Simplify the final result to have:
[tex]=log_364z^2-log(\frac{81}{9})\\=log_3(\frac{9(64z^2)}{81} )[/tex]
Hence the single logarithmic form f the expression is [tex]log_3(\frac{9(64z^2)}{81} )[/tex]

Is (2, 6) a solution to this system of equations?
y = x + 4
y = 9x + 10
Answer:
x=-1/5
y=41/5
I am not able to explain to you how I achieved these results, but at least you can try and see if you can solve the equation.
Answer:
No, (2,6) is not a solution to this system of equations.
Explanation:
Okay so lets restate the question:
Is (2, 6) a solution to this system of equations?
y = x + 4
y = 9x + 10
First, you find the x and y intercepts from the equations stated above.
y=x+4
x intercept(s): (-4,0)
y intercept(s): (0,4)
So for the first equation, (2,6) is not a solution.
Now, we find the x and y intercepts for the second equation.
y=9x+10
x intercept(s): (-10/9,0)
y intercept(s): (0,10)
So for the second equation, (2,6) is not a solution.
Both equations do not have (2,6) involved.
And its 24 points not 48 :((((

The scale factor from rectangle you UVWX two rectangle STQR is
Answer:
The scale factor is 1/3
Step-by-step explanation:
Compare side length XW with RQ, the side length decreases from 15 to 5, which is a shrinking by a factor of 1/3, since 5 is 1/3 of 15. You can check this by comparing the sides WV with RS, and since 8 is 1/3 of 24, the scale factor is 1/3 going from UVWX to STQR.

Hello, I Am BrotherEye
Answer:
Multiply total meters by 100 to get total centimeters:
6 meters x 100 = 600 centimeters.
Now divide total centimeters by 2.554 to get total inches:
600 centimeters / 2.54 = 236.22 inches.
Rounded to the nearest inch = 236 inches.
Step-by-step explanation:
*Important!
You multiply the length of the value by 39.37
Meaning that if you have 6 meters you would

Answer:
n = -7
Step-by-step explanation:
n - 7/4 = 35/12 + 5/3n
subtract n from both sides of the equation:
-7/4 = 35/12 + 2/3n
convert -7/4 to -21/12:
-21/12 = 35/12 + 2/3n
add 21/12 to both sides:
0 = 56/12 + 2/3n
convert 2/3n to 8/12n:
0 = 56/12 + 8/12n
subtract 56/12 from each side:
8/12n = -56/12
multiply both side by 12:
8n = -56
divide both sides by 8:
n = -7

Answer:
5. is C which is 9.
6. is B which is 37.
Step-by-step explanation:
The first on is C. 9 because to find the interquartile range you need to subtract the upper quartile range by the lower quartile range. The upper is 16 and the lower is 7 so you do 16-7 which is 9.
The last question is B. 37 because the lower quartile range is first line in the box plot which is 37.
