Use the distributive property on right side and solve:

3x-6=22-x

4x-6=22

4x=28

x=7

So the solution is x=7

Hope this helped!

What is the slope of line PQ?

Anit [1.1K]

Answer:

Step-by-step explanation:

Slope of a line passing through two points $(x_1,y_1)$ and $(x_2,y_2)$ is given by the formula,

Slope = $\frac{y_2-y_1}{x_2-x_1}$

Slope of the line PQ passing through the two points P(-8, 2) and Q(4, 2) will be,

Slope ' $m_1$ ' = $\frac{2-2}{-8-2}$ = 0

Therefore, slope of the line PQ parallel to the x-axis = 0

Slope of the line MN passing through the points M(8, 6) and N(8, -8) is,

Slope ' $m_2$ ' = $\frac{6+8}{8-8}$ = ∞

Therefore, slope of the line MN parallel to y-axis is undefined.

Since, angle between the x-axis and y-axis is 90°,angle at the intersection point between the lines parallel to x and y axis will be 90°.

These lines are perpendicular to each other.

Andreyy89

Answer:

<h3>"In a linear regression model, the variable that is being predicted or explained is known as <u>_dependent variable</u> It is denoted by y and is often referred to as the response variable".</h3>

Step-by-step explanation:

Given that "In a linear regression model, the variable that is being predicted or explained is known as <u>dependent variable</u> It is denoted by y and is often referred to as the response variable".

Because linear regression models for variables are used to explain or predict the relationship between two variables.
The variable in the given model that is being predicted is called the dependent variable.
