Jack = 3 presents every 15 minutes
luke = 4 presents every 20 minutes
target = 20 presents wrapped per person
y = kx ; where k is the constant rate, x is the number of presents wrapped, y is the total number of minutes spent wrapping x number of presents.
we need to compute for the unit rate of each individual.
Jack: 15 minutes / 3 presents = 5 minutes per present
Luke: 20 minutes / 5 presents = 4 minutes per present
Jack:
y = 5 minutes per present * 20 presents = 100 minutes
Luke:
y = 4 minutes per present * 20 presents = 80 minutes
Yes this is an exponential function. One way we can determine this is to notice how each y term is multiplied by 6 to get the next y term
example: -2 times 6 = -12
another example: -12 times 6 = -72
The exponential function that models this data is y = -2*6^(x-1). Note how plugging in x = 1 leads to y = -2. Plugging in x = 2 leads to y = -12, and so on.
Answer:
B
Step-by-step explanation:
This is a positive anotation.
Hope this helps have a good day!
Let
x------> the number of multiple choice question
y------> the number of free response question
we know that
-----> equation A

-----> equation B
Substitute equation B in equation A
Find the value of x


therefore
<u>the answer is</u>
the number of multiple choice question are 
the number of free response question are 
Answer: = x² - 12x + 35
(x - 5)(x - 7)
= x² - 5x -7x + 35
= x² - 12x + 35
