Solve. Thank you so much! A picture is there. <3

-8

Step-by-step explanation:

47 = -7x -9

Add 9 to each side

47+9 = -7x-9+9

56 = -7x

divide each side by -7

56/-7 = -7x/-7

-8 = x

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.
