Answer:

Part a) $AB=15\ cm$

Part b) $AB=11.1\ cm$

Part c) $AB=3/5\ cm$

Part d) $AB=3s\ cm$

Step-by-step explanation:

see the attached figure to better understand the question

we know that

To find the length of the image after a dilation, multiply the length of the pre-image by the scale factor

Part a) we have

The scale factor is 5

The length of the pre-image is 3 cm

therefore

The length of the image AB after dilation is

$3(5)=15\ cm$

Part b) we have

The scale factor is 3.7

The length of the pre-image is 3 cm

therefore

The length of the image AB after dilation is

$3(3.7)=11.1\ cm$

Part c) we have

The scale factor is 1/5

The length of the pre-image is 3 cm

therefore

The length of the image AB after dilation is

$3(1/5)=3/5\ cm$

Part d) we have

The scale factor is s

The length of the pre-image is 3 cm

therefore

The length of the image AB after dilation is

$3(s)=3s\ cm$

HELP ASAP WILL GIVE BRAININST IF:

DiKsa [7]

Answer:

<em><u>slope is -7/8</u></em>

Step-by-step explanation:

ok

first remember these to formulas:

$m= \frac{y2-y1}{x2-x1}$

and

$y-y1 = m(x-x1)$

now insert the points:

$\frac{-3-4}{3-(-5)}$ = -7/8

slope intercept form:

y - 4 = -7/8(x - (-5)

y - 4 = -7/8(x + 5)

y = -7x/8 - 3/8

Have a nice day!

and if you have a question or if I did anything wrong please tell me.
