Answer:
Angle 3 is = to angle 2 because:
Angle 3 & angle 7 are corresponding angles, meaning they have the same measure.
Angle 7 & angle 2 are vertical angles, meaning they also have the same measure.
Therefore, if angle 7 is equal to angle 3, then angle 2 must also be equal to angle 3.
Hope this helps! Have a great day!
For this case we have that by definition of properties of powers and roots, it is fulfilled that:
![\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}](https://tex.z-dn.net/?f=%5Csqrt%20%5Bn%5D%20%7Ba%20%5E%20m%7D%20%3D%20a%20%5E%20%7B%5Cfrac%20%7Bm%7D%20%7Bn%7D%7D)
So:
![\sqrt [4] {9 ^ {\frac {1} {2} x}} = 9 ^ {\frac {\frac {1} {2}} {4} x} = 9 ^ {\frac {1} {8} x}](https://tex.z-dn.net/?f=%5Csqrt%20%5B4%5D%20%7B9%20%5E%20%7B%5Cfrac%20%7B1%7D%20%7B2%7D%20x%7D%7D%20%3D%209%20%5E%20%7B%5Cfrac%20%7B%5Cfrac%20%7B1%7D%20%7B2%7D%7D%20%7B4%7D%20x%7D%20%3D%209%20%5E%20%7B%5Cfrac%20%7B1%7D%20%7B8%7D%20x%7D)
So, we have to:
![\sqrt [4] {9 ^ {\frac {1} {2} x}} = 9 ^ {\frac {1} {8} x}](https://tex.z-dn.net/?f=%5Csqrt%20%5B4%5D%20%7B9%20%5E%20%7B%5Cfrac%20%7B1%7D%20%7B2%7D%20x%7D%7D%20%3D%209%20%5E%20%7B%5Cfrac%20%7B1%7D%20%7B8%7D%20x%7D)
Answer:

Option B
<span>(-4-x)-(3y-9x)
= </span><span>-4 - x - 3y + 9x
= 8x - 3y - 4</span>
