Answer:

Step-by-step explanation:
So we have the two functions:

And we want to find g(f(3)).
So, let's find f(3) first:

Multiply:

Subtract:

Therefore, we can substitute -1 for f(3):

Now, find g(-1):

Multiply:

Add:

And we're done!
So:

Answer:
Step-by-step explanation:
Use sum of internal angles formula 180°(n - 2)
<u>For regular 24-gon it is:</u>
<u>Each angle would be:</u>
I think it's 20. Sorry if it's wrong
4.80/(3/4) = 6.4 per pound
8.2 * 6.4 = $52.48
Solution: $52.48 for 8.2 pounds
It is a nice linear equation. Remember y=mx+b
b is the y intercept you'll see
m is the slope rise over run
