Find its x-coordinate.
Ilya [14]

Answer:

2.5

Step-by-step explanation:

The formula to find the midpoint of a line segment: (\frac{1}{2}x_{1} + \frac{1}{2}x_{2}, \frac{1}{2}y_{1} + \frac{1}{2}y_{2})

<u><em>Where:</em></u>

x_{1} = -5\\x_{2} = 10\\y_{1} = 9\\y_{2} = 8

1) Substitute the values into the midpoint formula.

(\frac{1}{2}*-5 + \frac{1}{2}*10, \frac{1}{2}*9 + \frac{1}{2}*8)

2) Solve it.

= (-2.5 + 5, 4.5 + 4)

= (2.5, 8.5)

Simplify (xy)^-3/(x^-5y)^3
Nesterboy [21]
Use:\\\\(a\cdot b)^n=a^n\cdot b^n\\\\a^n:a^m=a^{n-m}\\\\\left(a^n\right)^m=a^{n\cdot m}\\\\a^{-n}=\left(\frac{1}{a}\right)^{n}\\==================================\\\frac{(xy)^{-3}}{(x^{-5}y)^3}=\frac{x^{-3}y^{-3}}{(x^{-5})^3y^3}=\frac{x^{-3}y^{-3}}{x^{-15}y^3}=x^{-3-(-15)}y^{-3-3}=\boxed{x^{12}y^{-6}=\frac{x^{12}}{y^6}}
