If x=4 and w=-9 then solve -8(5 - 4x) + 6w

34

Step-by-step explanation:

-8(5 - 4x) + 6w

Let x= 4 and w = -9

-8( 5 - 4(4)) + 6(-9)

Parentheses first

-8 (5-16) -54

Multiply and divide

-8(-11) -54

88 -54

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
