Gabrielle is 14 years older than mikhail. The sum of thier age is 84. What is mikhails age

Mikhail is 35 years

Step-by-step explanation:

let mikhails age be k.

mikhail=k

Gabrielle=k + 14

k + k + 14=84

2k+14-14=84-14

2k=70

2k/2=70/2

k=35years

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
