Y = 98 -4.4x x = 9, y =​

y = 58.4 when x = 9

Step-by-step explanation:

Here y = 98 - 4.4x, and x = 9.  We are to find the value of y.

Substituting 9 for x, we get:

          y = 98 - 4.4(9), or

          y = 98 - 39.6, or

           y = 58.4

y = 58.4 when x = 9

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
