Dora is keeping track of the number of books she has read during the current school year. she has already read 4 books.
which equation shows the total number of books, y, dora will have read by the end of the school year?
a. y = 4x, where x represents the number of books dora has already read
b. y = x + 4, where x represents the number of books dora has already read
c. y = 4x, where x represents the number of books dora reads between now and the end of the year
d. y = x + 4, where x represents the number of books dora reads between now and the end of the year

Dora Dora Dora the explorer! Oh, sorry. The answer is D.

Step-by-step explanation:

step-by-step explanation: step 3 should really go to step seven, but anyway never mind.

1 ∠oln ≅ ∠lno

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
