Will give brainliest find the x -coordinate of the vertex, y -coordinate of the vertex, and the x -intercepts.
y = x^2 + 4x - 5

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.

1/4 because there is 4 grades.

600,000,000,000, or 6e14

step-by-step explanation:

i would say true? if the unit was informational and it "refreshed your understanding", then true.
