Answer:
The price including tax is $1,456.92
Step-by-step explanation:
First we need to convert our percentage into a decimal.
0.08
Now we need to multiply our price by the sales tax.
$1,349.00 × 0.08 = $107.92
Our sales tax is $107.92.
Added to our price it's $1,456.92.

Answer:
The solution of the system of equations will be:
![y=-12,\:x=-3](https://tex.z-dn.net/?f=y%3D-12%2C%5C%3Ax%3D-3)
Step-by-step explanation:
Given the system of equations:
![\begin{bmatrix}y-2x=-6\\ y-4x=0\end{bmatrix}](https://tex.z-dn.net/?f=%5Cbegin%7Bbmatrix%7Dy-2x%3D-6%5C%5C%20y-4x%3D0%5Cend%7Bbmatrix%7D)
Isolate
for
, ![y=-6+2x](https://tex.z-dn.net/?f=y%3D-6%2B2x)
![\mathrm{Subsititute\:}y=-6+2x](https://tex.z-dn.net/?f=%5Cmathrm%7BSubsititute%5C%3A%7Dy%3D-6%2B2x)
![\begin{bmatrix}-6+2x-4x=0\end{bmatrix}](https://tex.z-dn.net/?f=%5Cbegin%7Bbmatrix%7D-6%2B2x-4x%3D0%5Cend%7Bbmatrix%7D)
![\begin{bmatrix}-6-2x=0\end{bmatrix}](https://tex.z-dn.net/?f=%5Cbegin%7Bbmatrix%7D-6-2x%3D0%5Cend%7Bbmatrix%7D)
Isolate x for
, ![x=-3](https://tex.z-dn.net/?f=x%3D-3)
![\mathrm{For\:}y=-6+2x](https://tex.z-dn.net/?f=%5Cmathrm%7BFor%5C%3A%7Dy%3D-6%2B2x)
![\mathrm{Subsititute\:}x=-3](https://tex.z-dn.net/?f=%5Cmathrm%7BSubsititute%5C%3A%7Dx%3D-3)
![y=-6+2\left(-3\right)](https://tex.z-dn.net/?f=y%3D-6%2B2%5Cleft%28-3%5Cright%29)
![y=-12](https://tex.z-dn.net/?f=y%3D-12)
Therefore, the solution of the system of equations will be:
![y=-12,\:x=-3](https://tex.z-dn.net/?f=y%3D-12%2C%5C%3Ax%3D-3)
-(-3)^2-4(3)
Basically a - outside the parentheses means that you are to multiply by a -1. So the first pet would be 3^2 which is 9 and then 4*3=12 so, 9-12= -3
