5(x - 4)
You can use the distributive propery to solve this one.

First list the terms in the parenthesis:

x -4

then multiply both by five

5x -20

now substitute

(5 * 8) - 20
(40) - 20
40 - 20
20

Your answer is 20

Please give an accurate answer and show work.

Stells [14]

Answer:

3.06

Step-by-step explanation:

$\log_{5}(\dfrac{2}{3}x-2)+2=0\\\\\log_{5}(\dfrac{2}{3}x-2)=-2\\\\$

This means that 5 to the power of -2 is $(\dfrac{2}{3}x-2)$ , meaning that:

$\dfrac{2}{3}x-2=5^{-2}=\dfrac{1}{25} \\\\\dfrac{2}{3}x=\dfrac{51}{25} \\\\2x=\dfrac{153}{25} \\\\x=\dfrac{153}{50}=3.06$

Hope this helps!

Chose the correct description for the scatter plot below.

Lapatulllka [165]

Answer:

Step-by-step explanation:

I'm assuming that non-linear means that there is some type of association between the dots, they are just not in a straight line. Now, they definitely are NOT in a straight line, but they do appear to be falling in an exponential pattern. I would say that this is a non-liner association (exponential decay, to be specific).
