Question:
On January 1, 1980 a city had 100,000 people. During the
year 1,000 people died, 2,000 babies were born, 3,000 people
moved out, and 10,000 moved in. How many people were in
the city by the end of 1980?
Make a Selection:
A. 92,000
B. 104,000
C. 107,000
D. 108,000

Let's find out!

Today's my B'day!

So, to calculate this, we need a equation.

(Let x= # of people in 1980)

See? Easy... wait? It's not the solution?

Oh! Made a Mistake!

Why you always check!

There you go!

Even Experts can make mistakes!

Hope this helps!

P.S. Stay Safe!

FYI option D

D. 108,000

Step-by-step explanation:

100,000

- 1,000

+ 2,000

- 3,000

+ 10,000

108,000

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
