Answer:

x=-5

Step-by-step explanation:

3x+12= -3

   -12    -12

(subtract 12 from both sides because you want the variable by itself)

3x= -15

(divide by 3 so you can get x completely by itself)

x= -5 (final answer)

What are the maximum and minimum of the function f(x) = 0.9|-(x − 5)| + 7?
r-ruslan [8.4K]

Answer:

Maximum value:

the maximum value is \infty

Minimum value:

the minimum value is 7

Step-by-step explanation:

We are given function as

f(x)=0.9|-(x-5)|+7

Firstly, we will draw graph

we can see the graph

and then we can identify maximum and minimum

Maximum value:

We know that

the largest y-value means maximum value of f(x)

We can see that curve is moving upward

so, the maximum value is \infty

Minimum value:

We know that

the smallest y-value means minimum value of f(x)

we can see that

It starts from point (5,7)

so, the minimum value is 7

Zena needs an Actor. Actor A charges $250 in addition to $50 per day. Actor B charges $ 200 in addition to $60 per day. When do
Sav [38]

Well I like to start with a base number. Ten. Ten days.

--Without Initial Costs--

Actor A after 10 days -  $500

Actor B after 10 days -  $600

A after 15 days -  $750 + $250 = $1000

B after 15 days -  $900 + $200 = $700

A after 5 days -  $250 + $250 = $500 <|

                                                          /\ \/ -ANSWER

B after 5 days -  $300 + $200 = $500 <|

A after 3 days -  $150 + $250 = $400

B after 3 days -  $180 + $200 = $380

A after 8 days -  $400 + $250 = $650

B after 8 days -  $480 + $200 = $680

Now there, I did a whole bunch of em. Now to add the initial costs. (I did the adding on the same numbers that I just typed so it may be confusing that NOW I am saying to do it when it is already done. LOL)

Basically after all that, the answer is 5 days.

Hope this helps!
