Answer:
![\$10.70](https://tex.z-dn.net/?f=%5C%2410.70)
Step-by-step explanation:
Let
x-----> the number of miles
y ---> the total charge in dollars
we know that
The total charge must be equal to the flat fee ($3) plus the number of miles multiplied by $1.10 per mile
so
The linear equation is
![y=1.10x+3](https://tex.z-dn.net/?f=y%3D1.10x%2B3)
For x=7 miles
substitute in the equation and solve for y
![y=1.10(7)+3](https://tex.z-dn.net/?f=y%3D1.10%287%29%2B3)
![y=\$10.70](https://tex.z-dn.net/?f=y%3D%5C%2410.70)

Answer:
1/(5x^8y^13)
Step-by-step explanation:
To simplify this exponential expression we must use some of the laws of exponents, specifically the quotient law. The quotient law states that if the base is the same and you're dividing we subtract the exponents and so: ![\frac{a^m}{a^n}= a^{m-n}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%5Em%7D%7Ba%5En%7D%3D%20a%5E%7Bm-n%7D)
Therefore:
![\frac{3x^{-6}y^{-3}}{15x^2y^{10}} =\frac{x^{-6-2}y^{-3-10}}{5}=\frac{x^{-8}y^{-13}}{5}\\ \\\frac{1}{5x^8y^{13}}](https://tex.z-dn.net/?f=%5Cfrac%7B3x%5E%7B-6%7Dy%5E%7B-3%7D%7D%7B15x%5E2y%5E%7B10%7D%7D%20%3D%5Cfrac%7Bx%5E%7B-6-2%7Dy%5E%7B-3-10%7D%7D%7B5%7D%3D%5Cfrac%7Bx%5E%7B-8%7Dy%5E%7B-13%7D%7D%7B5%7D%5C%5C%20%20%5C%5C%5Cfrac%7B1%7D%7B5x%5E8y%5E%7B13%7D%7D)
