Correct the error in the following equation. y=x² +18x +71 y-71 = x2 - 18x – 18 y-71 - 18 = (x-9) y=(x-9)2 +89 A. The equation is correct. B. y-71- 18 = (x – 9) should have been y-71- 18 = (x–9)(x +9) instead. C. X? - 18x - 18 should have been x2 + 18x + 81 instead. D. The solution should be y= (x +9)2 +89 instead.

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.

im super bad at school but u for some reason need to have points to ask questions and you get points by answering so thats all im doing sorry for t r o l l i n g
