Write an equation parallel to the line

The easiest way to find a parallel equation is to write your equation in slope-intercept form. The general equation for slope-intercept form is y = mx + b, where m = the slope of the equation, b = the y intercept, and x and y are your variables.

You're given 5x + 10y = -4. 
1) Move 5x to the right side by subtracting 5x from both sides:
5x + 10y = -4
10y = -5x - 4

2) Divide both sides by 10 to get y by itself on the left. Simplify:
10y = -5x - 4\\
y = - \frac{5}{10} x -  \frac{4}{10} \\
y = - \frac{1}{2}  x -  \frac{2}{5}



<span>Remember that for parallel lines, the slope, m, is the same for both equations. You can make the y-intercept, b, whatever number you want.

When the equation is in slope-intercept form, </span>y = - \frac{1}{2} x - \frac{2}{5}, you can see that m =  - \frac{1}{2}. 

A parallel equation is in the form: 
y = - \frac{1}{2} x + b

Plug in anything you want for b. One example is: y = - \frac{1}{2} x + 3

-------

Answer: y = - \frac{1}{2} x + 3 (just one example)

In case of parallel lines
\frac{a1}{a2}  =  \frac{b1}{b2} \: not \: equal \: to \:  \frac{c1}{c2}
Where a1, b1 and c1 are the constants of the first equation and a2, b2 and c2 are the constants of the second equation
From first equation (5x+10y+4 = 0)
a1 = 5
b1 = 10
c1 = 4
So now what we want to do is to divide 5 by a number and 10 by another number to get the same result at the end
I'll divide 5 by 1 and 10 by 2 to get the same number 5
5/1 = 10/2
Then I'll divide 4 by any number to get a result other than 5
Let's say 4 (or any other number it can be positive as well as negative)
So
a2 = 1
b2 = 2
c2 = 4
Then now the last step is to write the equation using these constants
x + 2y +4 =0
x+2y= - 4
Therefore this equation is parallel to 5x+10y = - 4

Express the recurring decimal 0.034 as a fraction in its simplest form.
LiRa [457]

Answer:

\frac{17}{495} will be the fraction.

Step-by-step explanation:

Here the recurring decimal number is 0.0343434....

To convert this recurring decimal to fraction we assume,

x = 0.03434....   -------(1)

Now multiply both the sides with 100.

100x = 3.43434.... ------(2)

Now subtract equation (1) from equation (2).

100x = 3.43434

<u>      x = 0.03434</u>

99x = 3.4

x = \frac{3.4}{99}

  = \frac{34}{990}

x = \frac{17}{495}

Therefore, fraction that represents the decimal number is \frac{17}{495}

Answer:

4/3π - √3

Step-by-step explanation:

Pie piece of circle is area of circle x portion of circle

πr²*x/360 = π(2)²*120/360 = 4/3π

Then you must subract the non-right triangle area

1/2ab sin C = 1/2(2)(2) sin 120 = 2 * √3/2 = √3

4/3π - √3
