Solve the following system of equations <br> Y= -2x – 3<br> 4y + x =16
Aleksandr-060686 [28]

Answer:

(-4,5)

*View attached graph*

Step-by-step explanation:

y = -2x - 3

4y + x = 16

4y + x = 16

4(-2x - 3) + x = 16

-8x - 12 + x = 16

-7x - 12 = 16

     +12   + 12

-7x = 28

/-7    /-7

x = -4

4y + x = 16

4y + (-4) = 16

4y - 4 = 16

   + 4   + 4

4y = 20

/4     /4

y = 5

(x,y) -> (-4,5)

Hope this helps!

Examine the graph
enot [183]

Answer:

<em>The scale factor is 3</em>

Step-by-step explanation:

<u>Dilations</u>

A dilation is a transformation that produces an image that has the same shape as the original but has a different size.  

A dilation is described by the scale factor or constant of dilation and the center of the dilation.

We are given a triangle XYZ of coordinates given in the graph to the left:

X=(-1,1), Y=(-1,4), Z=(-2,1)

It was dilated to triangle X'Y'Z' with coordinates:

X'=(-3,3), Y=(-3,12), Z=(-6,3)

Note each coordinate of the dilated triangle is three times the coordinates of the original triangle, thus the scale factor is 3
