Sergio039 [100]

1. H+S=40

2. 19H+25S=922

From 1,

19H+19S=760

Subtract this from 2 to eliminate H,

19H+25S-19H-19S=922-760

6S=162

Solve for S, then use either equation to solve for H.

Translate<br> (x-2, y+D) then<br> rotate 90°<br> counterclockwise<br> (-1, 1)
IgorLugansk [536]

By taking (-1, 1) and translating it left by 2 and up by D we have (-3, 1+D)

Rotating 90° counterclockwise puts a negative on your y-coordinate and switches the x and y-coordinates.

Final answer:

(-1-D, -3)
