Recall that
, which is to say
has period
. This in turn means that
will have the same solutions as
for any integer
. So the general solution to the first case is
where
is any integer.
On the other hand,
but
for any value of
, so this equation has no (real) solutions for
.
A because it can be rearranged to the y = mx + c format. y = -1/40 x + 4
Answer:
The function that represents the cost in cents of ‘d' dozen gumballs is y = 10d .
Step-by-step explanation:
As given
If 30 gumballs can be purchased for 3 dollars .
i.e
30 gumballs = $3
Now find out the cost of one gumballs .
As 1 dollar = 100 cents
1 gumballs = 10 cents
Thus the cost of one gumball is 10 cents .
As d = dozen gumballs.
Let us assume that the cost for ‘d' dozen gumballs = y
Than the function becomes
y = 10d
Therefore the function that represents the cost in cents of ‘d' dozen gumballs is y = 10d .
