The student council at woodlands middle school is planning a field trip. they polled randomly selected teachers and students and asked what they want to eat for lunch. the results are shown in the table below. which of the following statements is true.

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

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

my computer is slow i can not see it sorry

the volume of a is 200

step-by-step explanation:

each container originally held 200ml. container a now has 80ml and container b has 320ml
