A. There was 12 cm of snow when Luke woke up. Every 4 hours, the snow amount tripled. Let x represent the number of 4 hour intervals.
B. Levi has 12 rubber ducks. Every year, he gets three more rubber ducks for
his
birthday. Let x represent the number of birthdays.
C. Lucy parents increase her allowance by 12 times the original amount every
five years. She started with an allowance of $3. Let x represent the number of
5 year
intervals.
D. Mara has three Hallmark ornaments on her Christmas tree. Each year, her
number of Hallmark ornaments increases by 12. Let x represent the number of
years.

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:

most likely the answer is a.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
