Given that AB has been dilated by scale factor 3 to form A'B', and by laws of dilation, the image is congruent to the pre image. This implies that the image will not change in any way whatsoever apart from the size. Hence the slope will remain the same. That means the slope of A'B' will be 3

Aneli [31]

Answer:

Smallest: 15,840 ft

Largest: 16,896 ft

Step-by-step explanation:

1 mi = 5,280 ft

Setup proportion to solve for the <u>smallest</u>:

$\frac{1mi}{5,280ft} =\frac{3mi}{xft}$

Do butterfly method and you should get this:

$xft=3(5280)\\x=15,840ft$

Setup proportion to solve for the <u>largest</u>:

$\frac{1mi}{5,280ft} =\frac{3.2mi}{xft}$

Butterfly method:

$xft=3.2(5280)\\x=16,896ft$

Answer:

small dogs= 5

large dogs= 3

Step-by-step explanation:

Step one:

given data

let the number of small dogs be x

and the number of large dogs be y

Ryan earns $5 for each small dog he walks and $8 for each large dog he walks.

He walked 8 dogs and made a total of $49

5x+8y=49----------1

x+y=8---------------2

x=8-y

5(8-y)+8y=49

40-5y+8y=49

collect like terms

3y= 49-40

3y=9

divide both sides by 3

y=9/3

y=3

put y= 3 in eqn 2

x+3=8

x=8-3

x=5
