The center of the dilation is the origin, and the scale factor is 2.

To find the coordinates of the points under this transformation, it is enough to multiply both coordinates of the points X, Y, and Z by 2.

Take a look at the dilation of point Z. To get to Z', both the x and y coordinate of Z must be multiplied by 2.


So, the coordinates are:

X'(8, 0); Y'(6, 4); Z'(4, -4).

Answer:

3x+y=2

Step-by-step explanation:

Just remember that standard form is expressed as Ax+By=C. I also attached a picture to prove that 3x+y=2 is the standard form equation that makes up the line.

Hope this helps and answers your question :)

Suppose that receiving stations​ X, Y, and Z are located on a coordinate plane at the points ​(6​,2​), ​(negative 2​,negative 4​
marin [14]

Answer:

  (2,-1)

Step-by-step explanation:

A graph is useful here. Points X and Y have coordinate differences of ...

  X -Y = (6, 2) -(-2, -4) = (6+2, 2+4) = (8, 6)

Then the distance between X and Y is ...

  d = √(8² +6²) = √100 = 10

The point 5 units from X and from Y is the midpoint of XY:

  E = (X +Y)/2 = ((6, 2) +(-2, -4))/2 = (4, -2)/2 = (2, -1)

The epicenter is (2, -1).

_____

The graph shows circles of radius 5 around X and Y, and a circle of radius 13 around Z. The circles intersect at the point (2, -1), the epicenter.

Solve the equation. Explain each step and identify the property used to reach each step.
Tom [10]

To isolate x, we will first subtract 0.8 from both sides.

0.6x + 0.8 = 1.4

-0.8 -0.8

0.6x = 0.6

Now all we have to do is divide both sides by 0.6, because it is the number besides x.

0.6x/0.6 = 0.6/0.6

x = 1

So you get the answer of x = 1.
