SBAC Test Prep - Week #2

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 altitude of an airplane in flight is shown in the graph below. Which statements about the airplane's flight are true? Mark all that apply.

• The airplane spent more time descending than it did ascending.

• 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.
