So u plug in both values of x
f(4)=12+4/5(4)= 15.2
f(8)=12+4/5(8)= 18.4
then u add the 2 answers together
15.2+18.4 = 33.6
then divide by 2
33.6/2=16.8

▹ Answer
<em>4 ÷ 2/3 = 6</em>
<em>1 ÷ 10/3 = 3/10</em>
<em>1 ÷ 4/7 = 1 3/4</em>
<em>9 ÷ 1/3 = 27</em>
<em>4 ÷ 5/4 = 3 1/5</em>
▹ Step-by-Step Explanation
4 ÷ 2/3 = 4 × 3/2 = 12/2 = 6
1 ÷ 10/3 = 1 × 3/10 = 3/10
1 ÷ 4/7 = 1 × 7/4 = 7/4 = 1 3/4
9 ÷ 1/3 = 9 × 3/1 = 27/1 = 27
4 ÷ 5/4 = 4 × 4/5 = 16/5 = 3 1/5
Hope this helps!

I can't give you all the answers to your hw.. but if there is a link somewhere on the page or in the left corner it says Kuta Software.. so maybe look that up for the answers?
Answer:
1. 
2. 
Step-by-step explanation:
1. Solution for 1st part.
Given:
Ben shared his post with 2 friends
Each of those friends shares with 3 more every day.
the number of shares triples every day.
From the data given above, we can make the following:

An exponential function is represented by:

where a is the initial value and b is the growth rate.
The exponential function for this case would be:

2. Solution for part 2.
Given:
Carter shared his post with 10 friends.
each share with only 2 people each day.
From the data given above, we can make the following:

An exponential function is represented by:

where a is the initial value and b is the growth rate.
The exponential function for this case would be:

(4x-3)(x+5) 4x^2+20x-3x-15
4x^2+17x-15
