Oblicz ile wynosi niewiadoma (a+1)-(-8)= -9

Step-by-step explanation:

I don't understand your language but if it's the solution;

(a+1)-(-8)= -9

Remove the parentheses

a+1+8= -9

Collect the like terms

a= -9-8-1

a= -18

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.
