Ling's long-distance cell phone plan costs $0.03 per minute for each call. ling does not want her monthly bill to exceed $30. solve the inequality 0.03m ? 30 to find the number of minutes m she can talk each month.

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 answer

b. they are parallel and will never intersect.
