The right option is A.

Answer: Option 'A' is correct.

Step-by-step explanation:

Since we have given that

Number of  DVDs    Height

           2                        18

           3                        27

           4                        36

Since there is direct proportion between number of DVDs and height.

We need to find if the number of DVDs is n, then height would be

\dfrac{2}{18}=\dfrac{n}{h}\\\\\dfrac{1}{9}=\dfrac{n}{h}\\\\h=9n

Hence, the rule for the height for n is h = 9n.

Option 'A' is correct.

Find the average rate of change for the given function from x = 1 to x = 2.
Nadusha1986 [10]

Answer:

2

Step-by-step explanation:

The average rate of change from x=1 to x=2 is the same as finding the slope of a line at x=1 and x=2.

So we are going to need to corresponding y coordinates.

What y corresponds to x=1? y=3

What y corresponds to x=2? y=5

So we have the ordered pairs (1,3) and (2,5).

Line the points up vertically and subtract vertically then put 2nd difference over 1st difference.

(2 , 5)

-(1  , 3)

-----------

1      2

The average rate of change is 2/1 or just 2.

Now since we were asked to find the average rate of change given the function was a line, it really didn't matter what two points you used on that line.

What are the distributive property 14k+35
malfutka [58]
I’m not too sure of what you are asking. But if you want an equivalent expression, it would be

7(2k+5)

Since 7 is the greatest common factor of both 14 and 35. 14/7=2. 35/7=5
