If ABC and DEF are complementary, then the value of x will be,
90 - ABC = x
90 - 53 = x
x = 37°
Answer:
is your average rate of change,
Step-by-step explanation:
average rate of change is
, by slope formula
simplify this to get
, which is the definition of the derivative as h goes to 0

since you defined x=a, we can substitute a for x and vice versa to find our derivative.

simplifying
(your average rate of change)
Step-by-step explanation:
The coefficients are 4, 5 and 7
There is no constant
The second one is right
