Answer:
n=1/2 after being simplified
Step-by-step explanation:
Use Division Distributive Property:
9^n-1=1/3^4n-1 then convert both sides to the same base
3^2(n-1) = 3^-(4n-1)
cancel the base of 3 on both sides
2(n-1) = -4n+1
then expand 2n-2=-4n+1
add 2 to both sides 2n=4n+1+2
simplify: -4n+1+2 to -4n+3
2n=-4n+3
add 4n to both sides: 2n+4n=3
simplify: 2n+4n to 6n
6n=3
divide both sides by 6
n=3/6
simplify and n=1/2

Answer:
![A=24](https://tex.z-dn.net/?f=A%3D24)
Step-by-step explanation:
For finding the area of a trapezoid you first have to use the correct formula which is
.
Now we plug in what we already know.
![A=\frac{1}{2}(b_1+b_2)h\\A=\frac{1}{2}(5+7)(4)](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7D%28b_1%2Bb_2%29h%5C%5CA%3D%5Cfrac%7B1%7D%7B2%7D%285%2B7%29%284%29)
Now we start with the parenthesis
![A=\frac{1}{2}(12)(4)](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7D%2812%29%284%29)
Now if you can, you can multiply the 1/2 and the 12 and the 4 using a calculator or mentally
![A=24](https://tex.z-dn.net/?f=A%3D24)
The transformation rule applied if the image is of the reflection over the mirror line x=0 for the shape on the coordinate plane is (x, y) → (-x, y) option second is correct.
<h3>What is geometric transformation?</h3>
It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
We have quadrilateral showing in the picture.
Transformation rule applied if the image is of the reflection over the mirror line x=0 for the shape on the coordinate plane.
(x, y) → (-x, y)
After the transforming the coordinate according to the transformation rule, we will get the image of the given figure
Thus, the transformation rule applied if the image is of the reflection over the mirror line x=0 for the shape on the coordinate plane is (x, y) → (-x, y) option second is correct.
