12. a) How many numbers of 5 digits can be formed from the digits 4, 5, 6, 7, 8, 9 (no digit being repeated)? How many of these numbers are divisible by 5? b) How many different even numbers can be formed from the 5 digits 3, 5, 6, 7, 8? odd numbers less than 1000 can be formed using the digits 0,2,4,5,7? c) How many vo​

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

need more info

step-by-step explanation:

dude thats to long figure it

step-by-step explanation:

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )
