Answer:
1. n is 1 or -1
2. x is 6 or -6
Step-by-step explanation:
1. |n| -4 = -3
|n| = -3 + 4
|n| = 1
so n = 1 or - 1
2) -3|x| = -18
divide both sides by -3
|x| = -18/-3
|x| = 6
so x = -6 or 6
Answer:

Answer:
Jamal predicts that 243 people will visit his site on the fifth day.
Step-by-step explanation:
Since Jamal launched a website for his custom shoe store, and on the first day, 3 visitors registered on the website, while on the third day, 27 visitors registered on the website, if Jamal uses an exponential function to model the data from the first and third days, to determine how many visitors will predict to register on the fifth day, the following calculation must be performed:
Day 1 = 3
Day 2 = 3 ^ 2 = 9
Day 3 = 3 ^ 3 = 27
Day 4 = 3 ^ 4 = 81
Day 5 = 3 ^ 5 = 243
Therefore, Jamal predicts that 243 people will visit his site on the fifth day.
Top, right because the numbers are increasing by the same amount (2 in this case).
