Danny’s grandmother made b buns and c cookies and wants to put p things on each plate. how many plates does she need? 20

The number of plates needed is (C + B)/P

Step-by-step explanation:

Ok, we have C cookies, B buns, and she wants to put P things in each plate.

The number of plates can be obtained by:

(C + B)/P = N

Where you divide the total number of things (cookies + buns) into the number P, that is the number that goes in each plate, and in this way, you find how many groups of P things there are, and that number of groups is equal to the number of plates needed.

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
