Equality Properties

Step-by-step explanation:

<u>Step 1: Define Equation</u>

2x + 10 = -4x - 9

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Add 4x on both sides:                    6x + 10 = -9
  2. Subtract 10 on both sides:             6x = -19
  3. Divide 6 on both sides:                  x = -19/6

<u>Step 3: Check</u>

<em>Plug in x into the original equation to verify it's a solution.</em>

  1. Substitute in <em>x</em>:                    2(-19/6) + 10 = -4(-19/6) - 9
  2. Multiply:                               -19/3 + 10 = 38/3 - 9
  3. Add/Subtract:                      11/3 = 11/3

Here we see that 11/3 does indeed equal 11/3.

∴ x = -19/6 is the solution to the equation.

One railroad track was laid out on the line y = 8x - 2 by the engineers in charge. Which of the following lines could have been
kvv77 [185]
Y = 8x - 2.....slope here is 8. A parallel line will have the same slope.

The other line would be : y = 4 + 8x (or y = 8x + 4).....because they both have the same slope, which makes the lines parallel to each other

Find z. Write your answer in simplest radical form.
lara [203]

\qquad \qquad\huge \underline{\boxed{\sf Answer}}

Let's solve ~

The given triangle is a right angled Triangle, so we can apply Trigonometric relations to find the required result ;

That is :

\qquad \sf  \dashrightarrow \:  \sin(30 \degree)  =  { \dfrac{z}{2 \sqrt{2} } }

\qquad \sf  \dashrightarrow \:  \dfrac{1}{2}  =  \dfrac{z}{2 \sqrt{2} }

\qquad \sf  \dashrightarrow \: z =  \dfrac{2 \sqrt{2} }{2}

\qquad \sf  \dashrightarrow \: z =  \sqrt{2}

So, the value of z is \sqrt{}{2}
