Answer:

x=−14

Step-by-step explanation:

Step 1: Subtract x from both sides.

3x+20−x=x−8−x

2x+20=−8

Step 2: Subtract 20 from both sides.

2x+20−20=−8−20

2x=−28

Step 3: Divide both sides by 2.

2x

2

=

Answer:

x = 9.33333333333

Step-by-step explanation:

How to solve...

3x + 20 = x - 8

     +   8 = x + 8

----------------------  ( add 8 on both sides )

  <u>3x + 28 = x</u>

 3x  + 28 = 3x

---------------------- ( divide 3x on both sides )

     <u>28 = 3x</u>

      3  =  x

---------------------- ( divide 28 by 3 )

x = 9.33333333333

15 points! Thanks so much!!
Georgia [21]
For this question it is the difference of two perfect squares. This means your final answer will be (2x - 5)(2x + 5). This answer is not listed so it would be none of the above.

After review, B technically works because it is the difference of two perfect squares. This allows you to take the square root of each term while ignoring the sign and then place that back in with the original sign.

The points (1, 5) and (0, –2) fall on a particular line. What is its equation in slope-intercept form?
Savatey [412]

The equation of the line in slope intercept form is y = 7x - 2

<h3>How to find the equation of a line?</h3>

The equation of the line can be solved with the following equation.

y = mx + b

where

  • m = slope
  • b = y-intercept

Therefore,

m = -2  - 5 / 0 - 1 = -7 / -1

m = 7

Hence, using (1, 5)

y = 7x + b

5 = 7(1) + b

5 - 7 = b

b = -2

Therefore,

y = 7x - 2

Hence, the equation of the line in slope intercept form is y = 7x - 2

(a) Identify the sample used in the study.

(b) What is the sample's population?

(c) Which part of the study represents the descriptive branch of statitics?

(d) Make an inference based on the results of the study?

Solution

A. The samples used is the hours of sleep and math test scores of the volunteers

B. The samples population is hours of sleep and math test scores of people in general

C. The part of the study that represent the descriptive branch of statistics is "three times more likely"
