If figure pqrs is dilated using a scale factor of 0.5 with the center of dilation at (0,0) , what are the coordinates of the vertices of the image p’q’r’s?

First we have to find the coordinates of P, Q , R and S .

And the coordinate of P is (2,2), Q is (6,4), R is (6,8) and S is (2,8) .

The given scale factor is 0.5

To find the coordinates of the quadrilateral after dilattion, we have to multiply each coordinate by 0.5 that is

Correct option is D

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
