Per meter? Well, if just including, ONLY, the measurement of JUST the meters itself, then..
6x2=12, and 12x21=252.
It cost a total of $252.
(Not sure about my answer, sorry if it ends up wrong :( )
Answer:
The answer is B, -4
Step-by-step explanation:
Subtract 4 on both sides
![-8x=32\\](https://tex.z-dn.net/?f=-8x%3D32%5C%5C)
Divide both sides by -8
![x=-4](https://tex.z-dn.net/?f=x%3D-4)
<h2>
The required "option A)
" is correct.</h2>
Step-by-step explanation:
We have,
![\log _{a}x](https://tex.z-dn.net/?f=%5Clog%20_%7Ba%7Dx)
To find, the value of
= ?
∴
, where a, b and x are positive
a ≠ 1 and b ≠ 1
We know that,
The logarithm identity,
![\log_{p}m=\dfrac{\log_{y}m}{\log_{y}p}](https://tex.z-dn.net/?f=%5Clog_%7Bp%7Dm%3D%5Cdfrac%7B%5Clog_%7By%7Dm%7D%7B%5Clog_%7By%7Dp%7D)
∴
= ![\dfrac{\log_{b}x}{\log_{b}a}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Clog_%7Bb%7Dx%7D%7B%5Clog_%7Bb%7Da%7D)
Where, b is the common base of logarithm
∴ The value of
= ![\dfrac{\log_{b}x}{\log_{b}a}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Clog_%7Bb%7Dx%7D%7B%5Clog_%7Bb%7Da%7D)
Thus, the required option A)
is correct.
To work out the percentage you would do the amount he ate, divided by the original amount, and then you would multiply the answer by 100.
4 / 10 is 0.4
0.4 * 100 = 40
He ate 40% of the cookies.

(-4, 2)
Step-by-step explanation:
when its reflected across the y-axis it goes from (x, -y) to (-x, y)
