Triangle ABC was dilated and translated to form similar triangle A'B'C'. On a coordinate plane, 2 triangles are shown. Triangle

A B C has points (0, 2), (2, 2), and (2, 0). Triangle A prime B prime C prime has points (negative 4, negative 1), (1, negative 1), and (1, negative 6). What is the scale factor of the dilation?

Answer:

The scale factor is measured to be 2.5.

Step-by-step explanation:

The triangles are depicted below.

In triangle ΔABC,

the side lengths are AB = 2 units, BC = 2 units

In triangle ΔA'B'C',

the side lengths are A'B' = 5 units, B'C' = 5 units.

The formula for the scale factor in a dilation is given by:

Scale factor = \frac{\textrm{New length}}{\textrm{Old length}}=\frac{A'B'}{AB}=\frac{B'C'}{BC}=\frac{5}{2}=2.5

Thus, the scale factor is 2.5.

Explain two ways you could solve 20 = 5(-3 + x)
Leona [12618]

Answer:

The solution to your inquiry can be found below

Step-by-step explanation:

First method

                      20 = 5(-3 + x)                   expanding this equation

                     20 = -15 + 5x                    combine like terms

                     5x = 20 + 15

                     5x = 35                            dividing by 5

                     5x/5 = 35/5

                     x = 7

Second method

                     20/5 = 5/5 (-3 + x)          divide both sides by 5

                     4  = -3 + x                        adding 3 to both sides

                     4 + 3 = -3 + 3 + x            simplifying

                     7 = x

Inessa [12570]
In order to utilize the leftover stock properly, the company must package the Zena's product, committing to include one of Xavier's product in each bundle. The Xavier set consists of one blue and one black ink refill, while the Yvonne set comprises two blue, three black, and one red ink refill, whereas the Zena set contains four blue, five black, and one red ink refill. The company has 11 blue, 14 black, and 3 red ink cartridge refills available. Thus, forming equations based on existing inventory would yield the required quantities for optimal packaging without any leftover supplies.
