Rewrite the expression in z to the n power. The expression I was given is: 1 over z to the negative 1 half power.

12345 [234]

Answer:

The equivalent expression is;

$\frac{1}{z^{-\frac{1}{2}}}=z^{\frac{1}{2}}$

Step-by-step explanation:

The given expression is:

$\frac{1}{z^{-\frac{1}{2} }}$

Recall that:

$\frac{1}{a^{-m}}=a^m$

In our case, $a=z$ and $m=\frac{1}{2}$ .

We use this property of exponent to obtain;

$\frac{1}{z^{-\frac{1}{2}}}=z^{\frac{1}{2}}$

Y = 3x - 4. Where would you start? How would you find other points?

Varvara68 [4.7K]

You plug the x values from the graph or table into the x so for example:
the first number on the x axis of the graph is 1 so you would plug 1 into the equation giving you y = 3(1) - 4 and you solve
