Answer:
6.12
1.39
4.12
12
Step-by-step explanation:
If y ∝ x, then y = kx.
So, the constant of proportionality is given by 
Case 1:
$18.36 for 3 pizzas
Therefore, the constant of proportionality is 
Case 2:
$4.17 for 3 pounds of bananas.
Hence, the constant of proportionality is 
Case 3:
$16.48 for 4 pounds of potatoes.
Hence, the constant of proportionality is 
Case 4:
2 cups of flour to make 24 cookies.
Hence, the constant of proportionality is 
(Answer)
To transform the function
to have the amplitude of 3, we need to multiply the constant 3 to the function f(x), so we have
To transform the function
to have the midline
we need to subtract
by 4, so we have
,
To transform the function
to have period of
, we need to divide the original period
by 4, so we have
. Note that it is the
gives the effect of dividing the points on x-axes by 4 and the period is read on x-axes
Hence, the full transformation is given
which is the last option
The answer is 3/5, or 60%
11 (comedies) + 19 (tragedies) = 30
30/50 = 3/5, or 60%
Substitute in y= equation into 2nd equation to start.
