Log, 2 + log 7(x – 5) = 2

85/7

Step-by-step explanation:

log2 + log7(x-5) = 2

log(14(x-5)) = 2

14x - 70 = 10²

14x = 170

x = 170/14

x = 85/7 or 12 1/7

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
