Answer:

Step-by-step explanation:
GIVEN: The weight, in pounds, of a newborn baby
months after birth can be modeled by the function
.
TO FIND: What is the y-intercept of the function and what is its interpretation in the context of the problem.
SOLUTION:
in 
if 

Hence y-intercept is 
the y-intercept in this represents the weight of baby just after he is born.
39, it is like the fibonacci sequence you take the 2 previous numbers and add them together to get the next number.
112oz(lb/16oz)+x≤22
7+x≤22
x≤15
So she can pack 15 more pounds without going over the limit.
C -3/2
Just multiply the second equation by -3/2
this will make the y term = -3/4y
so adding will eliminate the y terms.
Answer:C
