Step-by-step explanation:

1) (fg)(x) = f(x)·g(x) = (5x -2)·(1 -2x)

  = (5x)(1) -(2)(1) +(5x)(-2x) +(-2)(-2x)

  = 5x -2 -10x^2 +4x

  = 9x -10x^2 -2 . . . . matches A

2) (f+g)(-2) = f(-2) +g(-2) = (-5(-2) +1) +(-6(-2) +2)

  = 10+1 +12 +2 = 25 . . . . matches C

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.
