The function f(x)= -6x+11 has a range given by {-37,-25,-13,-1}.Select the domain values of the function from the list 1,2,3,4,5
andreev551 [17]
The range is {-37,-25,-13,-1}. So you need to figure out what four numbers from this list of numbers (1,2,3,4,5,6,7,8), when applied to this
function, ( f(x)=-6x+11 ), equals these numbers that are in the range {-37,-25,-13,-1}.

So you apply each of these numbers (1,2,3,4,5,6,7,8) into the function (f(x)=-6x+11)
one by one.

f(1)=-6(1)+11=5
f(2)=-6(2)+11= -1
f(3)=-6(3)+11= -7
f(4)=-6(4)+11= -13
f(5)=-6(5)+11= -19
f(6)=-6(6)+11= -25
f(7)=-6(7)+11= -31
f(8)=-6(8)+11= -37
As you can see, f(2),f(4),f(6),and f(8) equal the numbers that are in the range {-37,-25,-13,-1}.

THESE ARE SEPARATE QUESTIONS THAT I DECIDED TO COMBINE:
saul85 [17]

1).  Her walking pace is  (1.75 miles) / (50 minutes).

If you want it in units of (miles per hour), do it like this:

               (1.75 miles / 50 minutes) x (60 minutes / 1 hour)

           =  (  1.75 x 60 / 50 ) miles per hour.

2).  The average change was 

                         (30 - 45) degrees  / (5 minutes) .

I'm sure you can do the division and make an integer out of that.

3).  Each bracelet cost $3.10.
Caroline bought five of them, so she spent $3.10 five times.
Either do the multiplication, or else write down $3.10 five times
and do the addition.

4).  In order to factor the expression, the two terms would need
to have some common factor ... both terms need either a power
of 'x', or they need two numbers that have a common factor.
They don't both have an 'x', and 13 and 10 have no common factor.

5).  Todd earned 'T' dollars.
Twice what Todd earned is  2T .
$350 more than that is   2T+350 .
The question says that 2,500 is exactly that amount,
so you can write
                                                  2T + 350 =  2,500

Subtract 350 from each side:    2T           =  2,150

Divide each side by  2:              (you can finish it now)

What is the value of the function when x =2
Harrizon [31]

Answer:

To make this easier, first draw or imagine a vertical line at x=2

Find where the vertical line and the graph intersects.

Draw or imagine that point of intersection.

Now, draw or imagine a horizontal line that goes through the point of intersection.

That horizontal line tells us the the value of the function by passing through that mark that says "-2"

The function's value at x=2 is -2.

Have an awesome day! :)

What is the combined perimeter of these two rectangles?
GarryVolchara [31]

Answer:

D) 24x + 52

Step-by-step explanation:

The perimeter of the purple rectangle is

P =2(l+w)

   =2 (4x+5  + 2x+7)

Combine like terms

   =2 (6x+12)

Distribute

  = 12x +24

The perimeter of the white rectangle is

P =2(l+w)

P =2(3x+14 +3x)

Combine like terms

  =2(6x+14)

Distribute

 12x +28

Add the perimeters

12x +24 +  12x +28

24x +52
