A sequence can be described using the rule \( a_{n}=-2+3(n-1) \). Which is the value of the 20th term in this sequence?

A used book store buys a hardback book for \( \$ 1.50 \) and then sells it for \( \$ 5 \). Over time, the store sells the same number of books it buys. The store manager can use the equation \( P(x)=5 x-1.5 x \) to determine the store's profit, \( P(x) \), where \( x \) is the number of books that the store sells. Which statement about the book store is true based on the profit equation?

Which graph shows the solution of the system of equations?
