Answer:a) 870
b) 435
Step-by-step explanation:
a)
number of photos to be posted =n = 30
number of web pages on which they would be posted is 2
Since the order in which the photos appear on the web pages matters,
Number of ways = 30 permutation 2
=870 ways
b)
Since the order in which the photos appear on the web pages does not matter,
Number of ways = 30 combination 2
= 435 ways
When X = -9 Y = 1 you can find this by going to -9 on the x axis and finding where the line is there
