What is -4y-3=5-3y+6-19

1. First distribute your numbers (which is done in step #2.)
so 8x+12=68
Now subtract 12 from both sides of your equal sign to move the numbers all to the left side.
You get 8x=56
Now divide both sides by 8.
x=7

Answer:

y = 4x

Step-by-step explanation:

Answer:

area of the square = (SIDE)2

=( 4)^2

= 16 answer

Answer:

x=48

Step-by-step explanation:

(x-10)÷2=19

<u>x</u><u>-</u><u>1</u><u>0</u> =19

2

<u>(</u><u>x</u><u>-</u><u>1</u><u>0</u><u>)</u><u>×</u><u>2</u> =19×2

2

x-10=19×2

x-10=38

x=38+10

x=48

Given parameters:

Equation of the line given  2x - 7y = 13

Coordinates of points = -3, 8

Unknown:

Equation of a line perpendicular = ?

Solution;

 To find the equation of this line, simply find the negative inverse of the given line.

         m  =

          2x - 7y = 13 , this is an equation of a straight line

  let us write it in the form y = mx + c so as to derive the slope

        y and x are coordinates

         m is the slope

        c is the y intercept

  2x - 7y = 13;

        -7y = -2x + 13

  divide through by -7;

             y = +

The slope of this line is ;

           Now the slope of a line perpendicular to it will be ;

  the equation of the line will be;

        y  =

Since the coordinate of this line is (-3,8) , let us find C;

     y  = 8 and x = -3;

     8  = (-3) + C

         multiply through by 2;

 

    16 = 21 + 2C

    16 - 21  = 2C

      -5 = 2C

        C  =

Now the equation of the line is;

              y  =
