Answer:
The answer in each numeral is:
- <u>f(4) = 28</u>
- <u>f(10) = -19</u>
- <u>f(-5) = -33</u>
- <u>f(9) = -9</u>
Step-by-step explanation:
To obtain the result in each case, you must replace the variable (n) by the value that appears in the second case, I'll explain it with the first exercise:
- 1. f(n) = 5n + 8
- f(4) = ?
As you can see, in the second doesn't appear f(n), but f(4), that means you must replace the "n" in the equation by 4, if we do this, we obtain:
- 1. f(4) = 5*(4) + 8
- f(4) = 20 + 8
- <u>f(4) = 28</u>
The first answer is 28, now we'll continue with the next exercises:
- 2. f(n) = -2n + 1
- f(10) = -2*(10) + 1
- f(10) = -20 + 1
- <u>f(10) = -19</u>
- 3. f(n) = 6n - 3
- f(-5) = 6*(-5) - 3
- f(-5) = -30 - 3
- <u>f(-5) = -33</u>
- 4. f(n) = -n
- <u>f(9) = -9</u>
In this form, <u><em>you can prove the answers are: 28, -19, -33, and -9 respectively</em></u>.

:Done
Answer:
1/5 or 20%
Step-by-step explanation:
There are 10 total options
P( 5 or6) = number of 5's or 6's / total
=2/10
= 1/5
1/5 = 20%
A) just exchange the (y) for [f(x)]
