Answer: \dfrac{1}{16}x^{-5}y^{-2}z^{4}

Step-by-step explanation:

Given

Expression is \left(4xy^3z^{-2}\right)^{-2}\cdot x^{-3}y^4z^0

using the Exponent property that is

[(a)^b]^c=a^{b\cdot c}\\a^x\cdot a^y=a^{x+y}

Applying the above property

\Rightarrow \left(4xy^3z^{-2}\right)^{-2}\cdot x^{-3}y^4z^0=4^{-2}x^{-2}y^{-6}z^{4}\cdot x^{-3}y^4z^0\\\\\Rightarrow \left(4xy^3z^{-2}\right)^{-2}\cdot x^{-3}y^4z^0=4^{-2}x^{-2-3}y^{-6+4}z^{4+0}\\\Rightarrow 4^{-2}x^{-5}y^{-2}z^{4}=\dfrac{1}{16}x^{-5}y^{-2}z^{4}

Answer:

The slope is \frac{5}{4}

Step-by-step explanation:

Slope of a dataset:

The slope of a dataset, having two points, is given by the change in y values divided by the change in x values

In this question:

Two points:

x = 0, y = 8

X = 4, y = 13

The slope is:

m = \frac{13 - 8}{4 - 0} = \frac{5}{4}

The slope is \frac{5}{4}
