Magdalena said that −2(−1.5)(−0.3) = 1.8, because the factors of −1.5 and −0.3 are both multiplied by −2. So, she found that (3)(0.6) = 1.8. Did Magdalena find the product correctly?

• Yes, the product of 1.8 is correct.

• No, Magdalena made a sign error. The product is −1.8.

• No, Magdalena made a multiplication error. The product is 0.9.

• No, Magdalena should multiply only one of the factors by −2, so the product is −0.9.

Anthony runs a sporting goods store. The graph below tracks the number of basketballs he has in stock. Anthony draws a line of best fit and writes the equation y = 2/3x + 30 to model the number of basketballs, y, he has in stock after x days. Which statement about Anthony's equation is true?

• The data is linear, but only his slope is correct.

• The data is linear, but only his y-intercept is correct.

• The data is linear, but neither his slope nor y-intercept is correct.

• The data is not linear, so a line of best fit is not an appropriate model.

• The airplane changed its cruising altitude once during the flight.

• The airplane's initial rate of ascent and final rate of descent are equal but opposite.

• The airplane rose at a constant rate until reaching a cruising altitude of 30,000 feet.

• The airplane's altitude was neither increasing nor decreasing for about half the flight.

Consider the equation below. 3x – 2(x – 1) = a Jordan thinks that when a = 2, the equation has infinitely many solutions. Is Jordan correct?

• Jordan is correct. The equation has infinitely many solutions when a = 2.

• Jordan is incorrect. The equation has no solutions for any value of a.

• Jordan is incorrect. The equation has exactly one solution for any value of a.

• Jordan is incorrect. There are infinitely many solutions, but for a different value of a.
