A jeweler charges a flat fee of $180 for a custom bracelet in addition to a fee of $12.50 per hour for labor. The function f(x)=12.50x + 180 represents the total cost, in dollars, to produce a bracelet that takes x hours to make. The jeweler decides to offer a holiday promotion that decreases the flat fee by $30. The function f(x)=g(x) - 30 represents the new total cost, in dollars. Which statement is true?

• The graph of g(x) is a horizontal translation 30 units left from the graph of f(x).

• The graph of g(x) is a horizontal translation 30 units right from the graph of f(x).

• The graph of g(x) is a vertical translation 30 units down from the graph of f(x).

• The graph of g(x) is a vertical translation 30 units up from the graph of f(x).

Consider the graph of the linear equation. Which statement is true?

• The point (-2, 8) is a solution to the linear equation.

• The point (-1, 2) is a solution to the linear equation.

• The point (0, 2) is a solution to the linear equation.

• The point (4, 0) is a solution to the linear equation.

Which expression is equivalent to 169x² - 36?

• (13x - 6)²

• (13x - 6)(13x + 6)

• (13x + 6)²

• (13x + 6)(13x + 6)

An athlete has already run 3 miles before deciding to run farther. The total distance, in miles, is recorded at the end of every hour, n, since the athlete started running. If a(n)=6n + 3 models the situation, and n represents the term number, which set of numbers could represent possible values of n?

• {1, 2, 3, 4, 5}

• {1, 1.5, 2, 2.5, 3, 3.5}

• {-5, -4, -3, ..., 0}

• {-5, -4, -3, ..., 3, 4, 5}

• The cost to rent from Company 1 is 1/2 times the cost to rent from Company 2.

• The cost to rent from Company 1 is 2 times the cost to rent from Company 2.

• The cost to rent from Company 1 is 3 times the cost to rent from Company 2.

• The cost to rent from Company 1 is 25 times the cost to rent from Company 2.
