Answer:
0.57142857142
Step-by-step explanation:
We are given 4 points.
Using this, we can make an equation.
I got 
by using the slope formula.
So the equation we have is
Now, we can solve for how much peanut butter is used to make 25 packages by plugging in 25 for 
, which is the number of cracker packages.
We need to use 
teaspoons of peanut butter to make 25 packages of crackers.
Hope this helps.
頑張って!

I got 16 but not 100% sure if it’s right
Sorry if it’s wrong, I tried my best
Answers:
x = -8/5 or x = 8/5
Sum of the first ten terms where all terms are positive = 4092
========================================================
Explanation:
r = common ratio
- first term = 4
- second term = (first term)*(common ratio) = 4r
- third term = (second term)*(common ratio) = (4r)*r = 4r^2
The first three terms are: 4, 4r, 4r^2
We're given that the sequence is: 4, 5x, 16
Therefore, we have these two equations
Solve the second equation for r and you should find that r = -2 or r = 2 are the only possible solutions. If r = -2, then 5x = 4r solves to x = -8/5. If r = 2, then 5x = 4r solves to x = 8/5.
-----------------
To find the sum of the first n terms, we use this geometric series formula
Sn = a*(1 - r^n)/(1 - r)
We have
- a = 4 = first term
- r = 2, since we want all the terms to be positive
- n = 10 = number of terms to sum up
So,
Sn = a*(1 - r^n)/(1 - r)
S10 = 4*(1 - 2^10)/(1 - 2)
S10 = 4*(1 - 1024)/(-1)
S10 = 4*(-1023)/(-1)
S10 = 4092
