Do your best i need it quickly sorta, if you do a weird answer just for the points i will report you.
solong [7]

Answer: See below

Step-by-step explanation:

For this problem, we are given four functions, and their domains. All we have to do is figure out which equation we want to plug x into and solve.

f(-20)

For this first problem, we have x=-20. Then we can eliminate equations 1, 2, 4. We know equation 3 is the correct one because it says x<-12. -20 is less than -12. Therefore we plug in x=-20 to the third equation.

f(-20)=3(-20)-7              [multiply]

f(-20)=-60-7                  [subtract]

f(-20)=-67

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

f(0)

For this problem, we have x=0. Then we can eliminate equations 1, 2, 3. We know equation 4 is the correct one because it says x∈{-15, -12, 0, 10}. This means x has to be either one of the four numbers listed in the parentheses. We see that x=0 is in there. Therefore we plug in x=0 to the fourth equation.

f(0)=11-|-0-1|             [subtract]

f(0)=11-|-1|                [absolute value]

f(0)=11-1                    [subtract]

f(0)=10

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

f(15)

For this problem, we have x=15. Then we can eliminate equations 2, 3, 4. We know equation 1 is the correct one because it says x>10. This means x has to be greater than 10. 15 is greater than 10. Therefore we plug in x=15 to the first equation.

f(15)=\frac{1}{|15+1|-11}       [add]

f(15)=\frac{1}{|16|-11}           [absolute value]

f(15)=\frac{1}{16-11}             [subtract]

f(15)=\frac{1}{5}

harkovskaia [24]

Answer:

60480

Step-by-step explanation:

This question has to do with permutations. A permutation is used to find the number of possible outcomes, assuming order matters. In this case, n=9 and r=6. This is written as _{9}P_{6} which equals \frac{9!}{(9-6)!}. Then, plug this into a calculator to get 60480.
