Arecipe for chocolate cake calls for 3.5 cups of flour the recipe makes seven servings how many cups of flour are needed to make ten servings. a. 5. b. 7. c. 3.5. d. 4. hurry

A. 5 cups

Step-by-step explanation:

3.5/7 = 0.5

0.5 cups per server

0.5 * 10 = 5

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
