Answer:
C
Step-by-step explanation:
Here, we want to interpret what is meant by m(10) = k
Originally M(n) represents the fee in dollars for an nth drive
So M(10) will represent the fee in dollars for the 10th drive and is equal to K dollars
Correct option is C
$2.49 -------------------100 %
$1.99 ------------------- x %
-------------------------------------
2.49 : 1.99 = 100 : x
x = ( 1.99 * 100 ) / 2.49 = 79.9 %
100 % - 79.9 % = 21.1 % ( Decrease )
$1.99 -------------------- 100 %
$2.49 -------------------- x %
------------------------------------
1.99 : 2.49 = 100 : x
x = ( 2.49 * 100 ) / 1.99 = 125.1 %
125.1 % - 100 % = 25.1 % ( Increase )
The percents of change are not the same.
The greater change is during the increase of price ( 25.1 % > 21.1 % ).

Answer:
(x - 5)² = 39
Step-by-step explanation:
Given
x² - 10x = 14
To obtain an equivalent equation use the method of completing the square.
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 5)x + 25 = 14 + 25
(x - 5)² = 39
