Abc is translated 2 units down and 1 unit to the left. then it is rotated 90° clockwise about the origin to form ? a? b? c? . the coordinates of vertex a? of ? a? b? c? are . the coordinates of vertex b? of ? a? b? c? are . the coordinates of vertex c? of ? a? b? c? are .

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

1 mph

step-by-step explanation:

if the question is asking how much does she drive per mile then,

13 / 13 = 1 mph
