Ther ratio of the number of adults to the number of students at the prom has to be 1: 10. last year there were 477 more students than adults at the prom. if the school is expecting the same attendance this year, how many adults have to attend the prom?

53 adults

Step-by-step explanation:

Let

x---------> the number of adults

y -------> the number of students

we know that

-----> equation A

-----> equation B

Equate equation A and equation B

solve for x

therefore

There are 53 adults

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
