Acity planner is measuring the distance of one city block. which unit of measure should she use: 1 mile, 1 meter, 1/2 inch. explain.

Meters

Step-by-step explanation:

Miles are to big to measure the distance of a city block, and inches are too small.

If she were to use inches, the number of the measure would be too large, and not easy to imagine and of she were to use miles, it would be a  little number (like a fraction or decimal number), that wouldn't be as easy to understand. Instead, using meters, the measurements wouldn't be too little or to big, they would be between 50 or 150 meters on average, so these are numbers more usable and practical.

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
