Answer:

   =9.4

Step-by-step explanation:

The median  is the middle of the numbers when lined up from smallest to largest

(n, n+5, n+6, n+9, n+15)

The median is n+6

n+6 = 9

Subtract 6 from each side

n +6-6 = 9-6

n = 3

The numbers are

(n, n+5, n+6, n+9, n+15)

3, 8 ,9 ,12, 15

The mean is where you add up all the numbers and divide by the number of numbers

mean = (3+8+9+12+15) /5

         = (47)/5

         = 9 2/5

        =9.4

Carl claims that for some centers of dilation of a line, the line will remain
RoseWind [281]

Answer:

Option C.

Step-by-step explanation:

Dilation of a line:

If center of dilation lies on the line, then the line remains same.

If center of dilation does not lies on the line, then the dilated line is parallel to the original time.

The given equation of line is

y=5x-10

The line will remain same if center of dilation lies on this line.

For x=0,

y=5(0)-10=-10\neq 10

It means (0,0) does not lies on given line.

For x=-5,

y=5(-5)-10=-35\neq 35

It means (-5,35) does not lies on given line.

For x=1,

y=5(1)-10=-5

It means (1,-5) lies on given line.

For x=2,

y=5(2)-10=0\neq 20

It means (2,20) does not lies on given line.

Center of dilation (1,-5) could be used to support Carl's claim.

Therefore, the correct option is C.

The length of a rectangle is 3 inches more than its width. The perimeter of the rectangle is 34 inches
kap26 [50]
<span> Perimeter <em>p</em> means adding up the four sides of a rectangle.

Step 2. Let <em>w</em> equal the width.

Step 3. Let <em>w+3</em> equal the length.

Step 4. Then you'll have this really confusing equation:  P=w+w+w+3+w+3=4w+6=30

And it will give you <em>w= 6</em>
