Using the cross product property on this proportion gives us the following equation:
6 (3x + 3) = 7 (x + 16)
Use the distributive property
18x + 18 = 7x + 112
Subtract both sides by 7x
11x + 18 = 112
Subtract both sides by 18
11x = 94
Divide both sides by 11
x = 94/11
This fraction is already fully simplified and cannot be simplified further. This should be your answer.
Let me know if you need any clarifications, thanks!
Answer:
-3, 2 , 3.3 , 4.6, 5.9
Step-by-step explanation:
I just counted where the dots were for example "-5"
Answer: C
Step-by-step explanation:
The formula to find average rate of change is 
. Since the problem is asking for the average rate of change from the second to fifth year, we plug in a=2 and b=5.
f(5)=420.4
f(2)=408.04
Now, we get 4.12 dollars per year for the average rate of change.

Answer:</h3>
B). y = (x -3)(x +1)(x -1)
<h3>
Step-by-step explanation:</h3>
The zeros of the function are -1, 1, and 3, so the factors are (x +1), (x -1), and (x -3).
Selection B is the only choice that has these three factors.

<em>Comment on zeros and factors</em>
When x = a is a zero of a polynomial function, (x -a) is a factor.
For the bubble numbers put the second box in there, and for the chart put the first box.
