Finding Image Points
The image of triangle ABC after a 180° rotation around
the origin is:
A'(-1,2)
B'(-4,2)
сол )
-2 AL
Can someone explain this to me please and thank you

i can explain it but i need the picture i think to answer it. basically what you do to the triangle rotated 180 on the origin is do a reflection. your original ABC points would be like this:

A(x,y)

B(x,y)

C(x,y)

and your new points would be labeled like this

A'(x,y)

B'(x,y)

C'(x,y)

obviously fill in the coordinates. another way to think about it without the graph is flipping around the signs of your coordinates, like (+,+) becomes (-,-). I could be wrong, I took pre-algebra last year, but I think this is a right explanation.

Step-by-step explanation:

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
