During a timed test, alexander typed 742 words in 14 minutes. assuming alexander works at this rate for the next hour, which of the following best approximates the number of words he would type in that hour?

a) 53
b) 840
c) 3180
d) 44,520

c

Step-by-step explanation:

find the unit rate of 742/14 the unit rate will turn out to be 53 you then multiply by 60 since there are 60 minutes in a hour

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
