Answer:
40 degrees
Step-by-step explanation:
-10+40=30

Differentiate both sides with respect to
, treating
as a function of
:




At the point (0, 0), the derivative is

Let the number be x
Twice the number = 2x
42 decrease by twice the number:
42 - 2x
Percent change is
(New - old) / old
50 - 75 / 75
25 / 75 = .33333333....
To convert to a percent, multiply by 100
Percent decrease = 33.33%
