6(x + 3) - 2 &lt; 8(x + 5)
stira [4]

The answer is x>-12

First you must use distributive property to simplify.

6x+18-2

Then, you must subtract 18 on both sides

6x-2

Next, add 2 on both sides

6x

Then, subtract 8x on both sides

-2x

Finally, Divide both sides by -2. Don't forget to switch the equality sign because the variable was changed to a positive using division.

x>-12

Find the equation of the horizontal line at a height of -3.9.
Sholpan [36]

The equation of the line will be y = -3.9, and the height after rounding off will be -4.

<h3>What is a straight line?</h3>

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

\rm m =\dfrac{y_2-y_1}{x_2-x_1}

The horizontal line can be defined as:

y = a

Where a is the constant.

Here a = -3.9

y = -3.9

The height = -3.9 ≈ -4

Thus, the equation of the line will be y = -3.9, and the height after rounding off will be -4.
