How many ways can 5 people-a, b, c, d, and e-sit in a row at a movie theater if (a) a

and b must sit together; (b) c must sit to the right of, but not necessarily next to, b; (c) d

and e will not sit next to each other?

EABDC?

Explanation:
I don’t know who C must sit to the right of I was assuming A but not sure.

If A and B must sit next to each other and D and E cannot split D and E on either side of A and B. C doesn’t have to sit directly next to B but to the right of A so sit it next to D

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
