Answer:

$\displaystyle 8^{\frac{x}{3}}$

Step-by-step explanation:

The rules of exponents say ...

$\displaystyle\sqrt[a]{b^c}=b^{\frac{c}{a}}$

Here, you have a=3, b=8, c=x, so the alternate form is ...

$\displaystyle 8^{\frac{x}{3}}$

Determine whether the three points are collinear.<br> (0, - 10). (-3,- 13), (2,-8)

LUCKY_DIMON [66]

Answer:

<h2>YES. These points are collinear.</h2>

Step-by-step explanation:

If three points are collinear, then the slopes are the same.

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

For (0, -10) and (-3, -13):

$m=\dfrac{-13-(-10)}{-3-0}=\dfrac{-13+10}{-3}=\dfrac{-3}{-3}=1$

For (-3, -13) and (2, -8):

$m=\dfrac{-8-(-13)}{2-(-3)}=\dfrac{-8+13}{2+3}=\dfrac{5}{5}=1$

We can check the last pair (0, -10) and (2, -8):

$m=\dfrac{-8-(-10)}{2-0}=\dfrac{-8+10}{2}=\dfrac{2}{2}=1$

Now try 50 for x. If x=50,what I'd y when y=x-20? Does that work with the other equation?

SSSSS [86.1K]

X= 50
Replace the x with the given number.
Y= 50-20
Y= 30
