Rectangle ABCD was dilated to create rectangle A'B'C'D.

77julia77 [94]

The first thing we must do for this case is to calculate the scale factor.

For this, we make the relationship between two parallel sides.

We have then:

$k =\frac{B'C'}{BC}$

Substituting values we have:

$k = \frac{9.5}{3.8}\\k = 2.5$

We are now looking for the value of AB

We have then:

$AB = \frac{A'B'}{k}$

Substituting values:

$AB = \frac{15}{2.5}\\AB = 6$

Answer:

The scale factor is:

$k = 2.5$

The value of AB is:

$AB = 6$

Solve x + 3y = 9. 3x – 3y = –13

Sloan [31]

$Question \ 1) \ x + 3y = 9$

$
x=9-3y
 
$ $|Subtract \ 3y \ from \ both \ sides|$

$Question \ 2) \ 3x - 3y = -13$

$
3(x-y)=-13
 
$ $|Factor \ out \ the \ common \ term \ 3|$

$x-y= \dfrac{13}{3}$ $|Divide \ both \ sides \ by \ 3|$

$x=- \dfrac{13}{3}+y$ $|Add \ y \ to \ both \ sides|$

$x=y- \dfrac{13}{3}$ $|Regroup \ terms|$
