3x+9+4x+x=
3x+9+4x+x=

-9/8

Step-by-step explanation:

3x + 9 + 4x + x

Collect like terms

3x + 4x + x = -9

8x = -9

Divide both sides by 8

8x/8 = -9/8

x = -9/8

answer: it would most likely be y=6 and 5/7.

step-by-step explanation:

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.
