Arecipe requires 12 cups of flour. you can only measure using 2/3 cups.
how many 2/4 cups are needed for this recipe?

18 cups

Step-by-step explanation:

I assume that the part about 2/4 is an error that really means 2/3.

All you need to do is divide 12 by 2/3. Since you can't divide by a fraction, you have to multiply by its reciprocal, 3/2. You get 36/2, or 18.

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
