- 1.3

Step-by-step explanation:

- 9 / 10 + - 2 / 5

= - 9 / 10 - 2 / 5

LCM of 10 and 5 = 10

2 / 5

= ( 2 / 5 ) x ( 2 / 2 )

= ( 2 x 2 ) / ( 5 x 2 )

= 4 / 10

- 9 / 10 - 2 / 5

= - 9 / 10 - 4 / 10

= ( - 9 - 4 ) / 10

= - 13 / 10

= - 1.3

1.3

Step-by-step explanation:

your welcome

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.

i cant answer this, theres no table. sorry man
