2[x]-4=6 whats the solution

Slav-nsk [51]

This is a simple equation that is easily solved.

2x-4=6 You just have to isolate the variable, which is x, to get the solution.

So what you can do, is to get rid of the -4 to isolate the variable by adding 4 to the other side of the equation.

2x-4 (+4)=6+4

2x=10

Then you can isolate the variable by doing the opposite action it says to do, so division.

x=5

A researcher is interested in the effects of exercise on mental health and he proposes the following study: Use stratified rando

Andre45 [30]

Answer:

Step-by-step explanation:

(a) The type of study described in the question is referred to as an experimental study.

(b) The treatment group is the group that exercises 2 times a week, whereas the control group is the group that does not exercise.

(c) Yes, the study under consideration makes use of blocking.

The blocking variables are 18-30-year-olds, 31-40-year-olds, and 41-55year olds.

(d) No, the study under consideration did not make use of blinding because the patients know if they are in the group that exercises or the one that doesn’t.

What is the slope of a line that is perpendicular to the line<br> y = 2x – 6?

Zolol [24]

Answer:

The slope of a line that is perpendicular to the line y = 2x – 6 is -1/2.

Step-by-step explanation:

The slope-intercept form of the line equation

$y = mx+b$

where

$m$ is the slope

$b$ is the y-intercept

Step 1:

Finding the slope of the given equation

The given equation is

$y = 2x - 6$

comparing with the slope-intercept form of the line equation

The slope of the equation is: m = 2

Step 2:

Determining the slope of the perpendicular line

In Mathematics, a line perpendicular to another line has a slope that is the negative reciprocal of the slope of the other line.

As the slope of the equation is: m = 2

Therefore, the slope of the new perpendicular line:

$-\frac{1}{m}=-\frac{1}{2}$

Hence, the slope of a line that is perpendicular to the line y = 2x – 6 is -1/2.

Important Tip:

The product of the slopes of perpendicular lines is -1.

<u>Verification:</u>

The slope of the given line:

$m_1=2$

The slope of the perpendicular line:

$m_2=-\frac{1}{2}\:\:\:\:$

The product of the slopes is:

$\:m_1\times \:m_2\:=2\times -\frac{1}{2}\:\:=-1$

As the product of the slopes of perpendicular lines is -1, therefore, the lines are perpendicular.

Thus, the slope of a line that is perpendicular to the line y = 2x – 6 is -1/2.
