Answer:
Option A.
Step-by-step explanation:
The given expression is,
![[(64)^{-\frac{1}{2}}]^{-\frac{2}{3}}](https://tex.z-dn.net/?f=%5B%2864%29%5E%7B-%5Cfrac%7B1%7D%7B2%7D%7D%5D%5E%7B-%5Cfrac%7B2%7D%7B3%7D%7D)
By solving the given expression,
[Since 
]
Now the expression will be,
![[(64)^{-\frac{1}{2}}]^{-\frac{2}{3}}=(\frac{1}{8})^{-\frac{2}{3}}](https://tex.z-dn.net/?f=%5B%2864%29%5E%7B-%5Cfrac%7B1%7D%7B2%7D%7D%5D%5E%7B-%5Cfrac%7B2%7D%7B3%7D%7D%3D%28%5Cfrac%7B1%7D%7B8%7D%29%5E%7B-%5Cfrac%7B2%7D%7B3%7D%7D)
![={(\sqrt[3]{8})^2}](https://tex.z-dn.net/?f=%3D%7B%28%5Csqrt%5B3%5D%7B8%7D%29%5E2%7D)
= 2²
= 4
Therefore, value of the given expression will be 4.
Option (A) will be the answer.
Answer:
Volume= 540 ft^3
Step-by-step explanation:
Since volume= length times Width times height, you do 3 times 6 times 30= 540 ft^cubed.
For the bottom you could switch the top row with the bottom and you would have to divide instead of multiplying

Answer:
(2,3)
Step-by-step explanation:
use the equal values method.
set y equal to itself.
y = -2x+7 but also 5x-7
-2x+7=5x-7 ............................. solve the equation
7x=14
x=2
Now substitute the x value into one of the equations given. for example i'll do -2x+7.
-2(2) +7 =y
-4+7=y
3=y
so thats your answer
x=2, y=3
(2,3)
