What are the slope between (-5,-2) and (8,13)​
Cerrena [4.2K]

Answer:

The slope:

m = \frac{15}{13}

Step-by-step explanation:

-To determine the slope of the following points shown, you need this formula:

m = \frac{y_{2} - y{1}}{x_{2} - x_{1}}

(m represents the slope, (x_{1}, y_{1}) represents the first coordinate and (x_{2},y_{2}) represents the second coordinate)

-Apply the following points to the formula:

m = \frac{13 + 2}{8 + 5}

Then, solve:

m = \frac{13 + 2}{8 + 5}

m = \frac{15}{13}

So, the slope is \frac{15}{13}.

What is 3 ^9? how to solve?
Tanya [424]
3⁹ is the same as doing:

3 * 3 * 3 * 3 * 3 * 3 * 3 * 3 * 3

What I would do it is narrow it down piece by piece. 

3 * 3 * 3 = 27. Do that 3 times, now you are left with:

27 * 27 * 27

27 * 27 or 27² = 729.

That leaves you with:

729 * 27

You can multiply by hand or use a calculator to get your answer of 19683.

To check your answer, plug 3⁹ into a calculator. Your answer should match this.
