Answer:
D
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
Here [ a, b ] = [ 2, 4 ]
From the table
f(b) = f(4) = 16
f(a) = f(2) = 4, hence
average rate of change = 
= 
= 6

Answer: $ 14
Step-by-step explanation:
Since, the cost of 1 pair of socks = x
The cost of 6 pair of socks = 6 x
Total amount spend = $ 40
According to the question,
6 x - 14 = 40
6 x = 40 + 14
6 x = 54
x = 9
Thus, the original price of one pair of socks = $ 9
⇒ The original price of 6 pairs of socks = $ 54
Hence, the total change = original price of socks - the price of socks in the sale = 54 - 40 = $ 14
P = 2(l+w)
substitute for P and l
12+8y = 2 (4x-2y+w)
distribute
12+8y = 8x -4y +2w
solve for w
subtract 8x from each side
12 +8y -8x = -4y+2w
add 4y to each side
12 +12 y -8x = 2w
divide by2
6 +6y-4x =w
the other side is 6+6y-4x
