You and your friends Jose and Sarah all live on the same street. You know that Jose lives five blocks from away from you. Jose says that Sarah lives two blocks from him, but he didn't say whether she lives closer to you than he does or further. Let b be the number of blocks Sarah might live from you

Kindly check explanation

Step-by-step explanation:

Given that:

Sarah, Jose and you live in the same street:

Distance between you and Jose = 5 blocks

Distance between Jose and Sarah = 2 blocks

Distance (b) between you and Sarah:

Since it isn't stated whether Sarah lives closer to you than Jose or vice versa ;

Then;

Distance b between you and Sarah will be :

(Distance between you and Jose ± distance between Jose and Sarah)

b = (5 ± 2)

b = (5 + 2) or (5 - 2)

b = 7 blocks or 3 blocks

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
