Answer:
f(X)=2x is the correct answer
<u>Given</u>:
The coordinates of the points A, B and C are (3,4), (4,3) and (2,1)
The points are rotated 90° about the origin.
We need to determine the coordinates of the point C'.
<u>Coordinates of the point C':</u>
The general rule to rotate the point 90° about the origin is given by

Substituting the coordinates of the point C in the above formula, we get;

Therefore, the coordinates of the point C' is (-1,2)
Answer:
A) infinitely many solutions
Step-by-step explanation:
2x - y = 8
4x - 2y = 16
simplify the first equation
2x - y = 8
2x = 8 + y
2x - 8 = y
y = 2x - 8
substitute y for 2x - 8 in the second equation
4x - 2y = 16
4x - 2(2x - 8) = 16
4x - 4x + 16 = 16
4x - 4x = 16 - 16
0x = 0
since no matter what x is, 0 = 0, the answer is infinitely many solutions
