Answer:

x < -2 or x > 10/3

Step-by-step explanation:

3x - 2 > 8

3x > 10

x > 10/3

-3x + 2 > 8

-3x > 6

x < -2

x < -2 or x > 10/3

Answer:

the solution set consists of {x < -2 ∪ x > 10/3}

Step-by-step explanation:

|3x - 2| > 8 is equivalent to the following set of inequalities:

1) 3x - 2 > 8

and

2) -(3x - 2) > 8

In case 1, above, add 2 to both sides, obtaining 3x > 10, or x > 10/3.

In case 2, above, carry out the indicated multiplication first:

-3x + 2 > 8.  Next, subtract 2 from both sides:  -3x > 6.

Next, divide both sides by -3, remembering to reverse the direction of the inequality sign:  x < -2.

Thus, the solution set consists of {x < -2 ∪ x > 10/3}

Readme [11.4K]

The flux across a surface is an indicator of the rate at which fluid is flowing through it when there is a fluid flowing in three dimensions and a surface positioned inside that space.

<h3>What is Electric Flux?</h3>
  • A feature of an electric field is electric flux. One way to conceptualize it is as the quantity of forces interacting in a specific space.
  • According to conventional wisdom, electric field lines begin with positive electric charges and conclude with negative charges.
  • A closed surface's field lines are seen as negative when they are directed into it, and as positive when they are directed out of it.
  • Every field line that is directed into a closed surface continues through the interior and is often directed outward somewhere else on the surface if there is no net charge present within the surface.
  • The net, or total, electric flux is zero because the size of the negative and positive fluxes are just about equal.
  • A closed surface that contains a net charge will have a total flux that is proportional to the enclosed charge, positive if it is positive and negative if it is negative.

The angles 3x+6 and 5x + 6 are supplements. What are the two angles
yarga [219]

Answer:

x = 21

Step-by-step explanation:

<u>Step 1:  Make an expression</u>

Since they are supplements, that means that they add up to 180 degrees.

3x + 6 + 5x + 6 = 180

<u>Step 2:  Combine like terms</u>

3x + 6 + 5x + 6 = 180

(3x + 5x) + (6 + 6) = 180

8x + 12 = 180

<u>Step 3:  Subtract 12 from both sides</u>

8x + 12 - 12 = 180 - 12

8x = 168

<u>Step 4:  Divide both sides by 8</u>

8x / 8 = 168 / 8

x = 21

Answer:  x = 21
