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

For , you start by determining which of the pieces the x-value of -20 fits into.

Wow, those are some convoluted conditions on the right.  

Eventually you see "x>20" on the first line/first piece of the function.  So that tells you that you need to use the first piece and for x=20, just treat the function as is it was

This means,

Can you finish that out from there?

Recap:

Step #1: figure out which piece your x-value fits with.

Step #2: plug in the x-value into that piece and evaulate it.

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.

      [add]

          [absolute value]

            [subtract]

the answer is stop cheating on things stoopid

step-by-step explanation:

im eatin up the 44

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:

x=17
