Polygon abcde is dilated by a scale factor of 3 with the center of dilation at the origin yo create polygon a’b’c’d’e’ if the end points of bc are b(3,5) c(5,10) what is the slope of b’c’

Hey mate. Here is your answer.

slope= 5/2

Solution and explanation:

Polygon which is dilated by a scale factor of 3.

The endpoints of BC are B (3,5) and C (5,10).

The image of B & C under the dilation would be:

B'=3(3,5)=(9,15)

C'=3(5,10)=(15,30)

The slope is given by change in y divided by change in x.

slope=(30-15)/(15-9)

=15/6

=5/2

Hope this helps you!

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
