Answer: x-2y=-10

Step-by-step explanation:

Write x - 2y = 6 in intercept form(y=mx+c).

2y =x- 6

y =dfrac{x- 6}{2}

y =dfrac{x}{2}-3

Here , slope of line  x - 2y = 6  = m=\dfrac{1}{2}  (Coefficient of x)

Also , the slope of two parallel lines are equal.  

Equation of line passing through point (a,b) and has slope m is given by :_

(y-b)=m(x-a)

Standard form of equation : Ax+By= C ,where A is  positive integer a,d B and C be any integer.

Equation of the line parallel to line  x - 2y = 6  and passing through (-2, 4)  will be :-

(y-4)=\dfrac{1}{2}(x-(-2))\\\\ 2(y-4)=(x+2)\\\\ 2y-2(4)=x+2\\\\2y-8=x+2\\\\ x-2y=-8-2\\\\ x-2y=-10\ \ {\text{(Standard form)}}

Rewrite the equation: 2y=x-6, y=x/2-3, so slope is 1/2 which is also the slope of the parallel line.
It will have the equation y=x/2+a where a is found by plugging in the given point: 4=-1+a, so a=5.
Therefore y=x/2+5. (This can also be written 2y=x+10 or x-2y+10=0)

(3+11i)/(3+11i)=1

So that means you can multiply 6/(3+11i) by (3+11i)/(3+11i)

Then 6(3+11i)/1

= 18+66i

Write the statement in the if then form perpendicular lines intersect to form right angles
kvv77 [185]

Answer: If perpendicular lines intersect, then they form right angles.


Step-by-step explanation:

You take the first part, "perpendicular lines intersect", and add the "if" to it. Then, you take the second part, "to form right angles", and add the "then" in front of it to get your answer, "If perpendicular lines intersect, then they form right angles."

Hope it helps! :)

For a recent year, 38 more Democrats than Republicans represented a country. If the total number of representatives of the count
Fantom [35]

Second question isn't well formatted

Answer:

Number of republicans = 207

Number of democrats = 245

Step-by-step explanation:

Let :

Number of republicans = x

Number of democrats = x + 38

Total number of representatives from the two parties = 452

Tge number of representatives from each party can be calculated thus ;

Number of democrats + number of republicans = total number of representatives

(x + 38) + x = 452

x + 38 + x = 452

2x = 452 - 38

2x = 414

x = 414 / 2

x = 207

Number of republicans = 207

Number of democrats = 207 + 38 = 245

Math help please TY :3<br><br> HWAJDSK 10 POINTS REWARDING !!
valkas [14]

I will do Point A carefully, The others I will indicate. Start with the Given Point A. Then do the translations

A(-1,2) Original Point

Reflection: about x axis:x stays the same; y becomes -y:Result(-1,-2)

T<-3,4>: x goes three left, y goes 4 up (-1 - 3, -2 + 4): Result(-4,2)

R90 CCW: Point (x,y) becomes (-y , x ) So (-4,2) becomes(-2, - 4): Result (-2, - 4)

B(4,2) Original Point

  • Reflection: (4, - 2)
  • T< (-3,4): (4-3,-2 + 4): (1 , 2)
  • R90 CCW: (-y,x) = (-2 , 1)

C(4, -5) Original Point

  • Reflection (4,5)
  • T<-3,4): (4 - 3, 5 + 4): (1,9)
  • R90, CCW (-9 , 1)

D(-1 , -5) Original Point

  • Reflection (-1,5)
  • T(<-3,4): (-1 - 3, 5 + 4): (-4,9)
  • R90, CCW ( - 9, - 4)

Note: CCW means Counter Clockwise

The graph on the left is the same one you have been given.

The graph on the right is the same figure after all the transformations
