Answer:

The answer in each numeral is:

f(4) = 28
f(10) = -19
f(-5) = -33
f(9) = -9

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
f(4) = 28

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
f(10) = -19

3. f(n) = 6n - 3
f(-5) = 6*(-5) - 3
f(-5) = -30 - 3
f(-5) = -33

4. f(n) = -n
f(9) = -9

In this form, you can prove the answers are: 28, -19, -33, and -9 respectively.

7(x+2)

Let's find the common term in this expression to factor it out. it is 7.

Factoring is the opposite of distributing.

If we distribute, we will get the original expression.

45-27k

Here, the common term is 9:

9(5-3k)

12ab+7b - the common term is b:

b(12a+7)

y^2-9y.

Here the common term is y:

y(y-9)

8r-32r² the common term here is 8r:

8r(1-4r)

16gh+28gh: the Common Term is 4gh:

4gh(4+7)

21w²-77wx The common term is 7w:

7w(3w-11x)

Hope it helps! Please mark Brainliest! =)

Jericho is doing a quick survey for his high school newspaper. He hands out a simple index card to 100 seniors in his high schoo

Kazeer [188]

Answer:

Step-by-step explanation:

From research among high school students in the US, it was discovered in 2017 by US Centre for Disease Control and Prevention Agency(USCDC), that around 57.8% of high school students have drank alcohol in the previous 1 year.

Now, applying it to this question, since the survey is done among 100 seniors, the most modest probability would likely be 50% which represents 50 people out of the 100 surveyed that will likely check yes
