PLZ HELP DESPERATE NO LINKs! Will mark brainliest

Step-by-step explanation:

y is 40 and x is 21

so xy=61

Y=40

X=21

XY=61

I hope you have a spectacular day and take mental health breaks!

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.
