The vertices of rectangle LMNO are shown. L(-7, 6), M(-3, 6), N(-3, 3), 0( – 7, 3)
The rectangle is rotated 90° counterclockwise about the origin.
What are the coordinates of M', the image of point M after the rotation?
A. (3,6)
B. (6, 3)
C. (-3, -6)
D. (-6, -3)

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!
