Make a number line and show all values of x such that x≤1 2/3 and x<− 3/4

x < -¾

Step-by-step explanation:

And is the Intersection, which is the common region

x < -¾ and x < 1⅔

has a common region of x < -¾

Draw a number line with open circle at -¾, going towards left of -¾

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.

the answer

b. they are parallel and will never intersect.
