37. A designer sketches a design for a tabletop on graph paper. The table is
    bounded by a parabola and a line. The parabola can be modeled by the function
    y = 2x2 - 3x + 2. The line intersects the parabola when x = -1 and when x = 3.
    What is an equation of the line?
    CD y = —x + 8
    CD y = x + 8

CO y = 2x + 5

CO y= -2x + 5

38. Which equation illustrates the Distributive Property?
    CD 4(x + 2) = 4x + 8 C O 4(jc + 2) = 4(2 + x)
    CO 4(x + 2) = (x + 2)4 CD 4(x + 2) = 4(x + 2)


39. Which rate is equivalent to 30 m/s?
    C D 3 km/h C D 108 km/h


40. Which of the following is equivalent to 0.05%?
    CD 0.00005 CO 0.0005

CO 3000 km/h

CO 0.005

CO 108,000 km/h

CD 0.05

41. A box with 4 balls weighs 5 lb. The same box with 10 balls weighs 11 lb. Write an

equation in slope-intercept form for the weight y of a box containing x balls. Then

rewrite the equation in standard form using integer coefficients.
