Which of the following rules best describes the matrix below? (Picture)
2 answers:
Answer:
The correct option is b.
Step-by-step explanation:
The rule of rotation of 90° counterclockwise about the origin is defined by the matrix

The rule of reflection of the line y=x is defined by the matrix

The rule of rotation of 180° about the origin is defined by the matrix

The rule of translation of 1 unit left and 1 unit up is defined by the matrix

Only the rule of reflection of the line y=x is defined by the given matrix, therefore the correct option is b.
Answer:
option b
reflection over the line y = x

Answer:
32º
Step-by-step explanation:
Fº-32 ×5/9
5/9Fº-160/9
5/9Fº =160/9
(5Fº)9=9(160)
45Fº=1440
divide both sides by 45
Fº=32
