(07.02 LC) What is the sum of the arithmetic sequence 3, 9, 15 …, if there are 26 terms?

(05.05 LC) Which of the following represents the graph of f(x) = 3x + 1?

(07.03) What is the sum of an 8-term geometric series if the first term is −11, the last term is 859,375, and the common ratio is −5?

(07.02 LC) What is the sum of the arithmetic sequence 3, 9, 15 …, if there are 24 terms?

(06.01 MC) Solve the system of equations below. x + y = 83x + 2y = 21

(07.01) Given the arithmetic sequence an = 4 − 3(n − 1), what is the domain for n?

(05.02 MC) The function f(x) = 2(3)x represents the growth of a dragonfly population every year in a remote swamp. Rose wants to manipulate the formula to an equivalent form that calculates seven times a year, not just once a year. Which function is correct for Rose’s purpose, and what is the new growth rate?

(06.03 MC) Which of the graphs below correctly solves for x in the equation −x2 − 6x + 5 = 2x + 5?

(05.01 MC) Solve 25 = 5x − 4.

(07.01) Arthur has decided to start saving for a new computer. His money is currently in a piggy bank at home, modeled by the function s(x) = 85. He was told that he could do the laundry for the house and his allowance would be a(x) = 10(x − 1), where x is measured in weeks. Explain to Arthur how he can create a function that combines the two, and describe any simplification that can be done.
