Answer:  22) A

<u>Step-by-step explanation:</u>

First, order doesn't matter so it is a Combination.

<em>In other words, it doesn't matter which person was chosen 1st, 2nd, 3rd, or 4th to bring food because they are all bringing "food".</em>

Next, If you are going to choose  person to 4 people to bring food out of a total of 4 + 3 + 1 = 8 people, you get → ₈C₄

And you are going to choose 3 people to bring decorations out the remaining 8 - 4 = 4 people, you get → ₄C₃

And you are going to choose 1 person to be the host out of the remaining 4 - 3 = 1 person, you get → ₁C₁

"And" means multiplication so altogether you get ⇒  ₈C₄ × ₄C₃ × ₁C₁

Please help me please
Phoenix [80]

Answer:

x = 36

Step-by-step explanation:

The angles 3x - y and 2x + y form a straight angle and are supplementary, so

3x - y + 2x + y = 180

5x = 180 ( divide both sides by 5 )

x = 36

-----------------------------------------------

5y and 3x - y are vertical angles and congruent, hence

5y = 3x - y ( add y to both sides )

6y = 3x ← substitute x = 36

6y = 3 × 36 = 108 ( divide both sides by 6 )

y = 18

F(-12) if f(x) = 2x + 15
Alenkinab [10]

Answer: f(-12)=-9

Step-by-step explanation:

We have the following function:

f(x)=2x+15

And we have to evaluate it when x=-12, this means we have to substitute x by -12:

f(-12)=2(-12)+15

Solving:

f(-12)=-24+15

Finally:

f(-12)=-9
