If the distance from the center of dilation to one line is 9, and the distance from the center of dilation to a parallel line is 2.5, what scale factor should be used to map the first line onto the second? A. The scale factor is the distance of the mapped image times the distance of the original image, 2.5×9=22.5

B. The scale factor is the distance of the original image over the distance of the mapped image, 92.5=3.6

C. The scale factor is the distance of the mapped image over the distance of the original image, 2.59≈0.28

D. The scale factor is equal to half of the distance to the original image, 92=4.5

false.

step-by-step explanation:

false.

cavalieri's principle makes that statement about the volumes, not about the areas.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

step-by-step explanation:

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

so, converting firstly the mixed fractions to improper fractions and then "adding".
