10 points A cell phone data plan has a monthly charge of $30 and charges $15 for each
additional 10 gigabytes of data. The function below can be used to determine
the cost of the cell phone plan for any month. What are the rate of change and
initial value?
y = 15x + 30

A. The initial plan cost is the y-intercept of 30 and the rate of change is $15
for each additional 10 gigabytes.

B. The initial plan cost is the y-intercept of 10 and the rate of change is $15
for each additional 10 gigabytes.

C. The initial plan cost is the y-intercept of 10 and the rate of change is $30
for each additional 10 gigabytes.

D. The initial plan cost is the y-intercept of 15 and the rate of change is $30
for each additional 10 gigabytes

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.

step-by-step explanation:

i think you should think about the question and not look online.

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour
