Which of the following best describes how the y values are changing over each interval? x y 1 20 2 40 3 80 4 160 5 320 they are increasing by 20 each time. they are increasing by 40 each time. they are being multiplied by 2 each time. they are being multiplied by 4 each time.

They are being multiplied by 2 each time.

Step-by-step explanation:

The y-values are

20, 40, 80, 160, 320

To get the second value, 40, from the first, 20, we can either add 20 or multiply by 2.

To get the third value, 80, from the second, 40, we can either add 40 or multiply by 2; since the relationship needs to be the same each time, it is multiplying by 2.

the y valves are increasing by 4 each time.

Step-by-step explanation:

if you add 4 each time it is correct on e2020 and edge.tell me if you agree i would love to help.

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.
