14/N= 14 divided by _____ = 1.75
7/4= 1.75
(Numerator divided by denominator)
So, now fill in the blank, which is your variable. (N)
Answer:
C
Step-by-step explanation:
F(x) = x² + 7x + 8
f ¹ (x) = d/dx (x² + 7x + 8)
= (2*x) + (7*1) + h
= 2x + 7 + h
Step-by-step explanation:
For this composition function, , we should substitute anytime we see an variable in :
First, add 84 to both sides, to isolate the exponential function.
Then, take the logarithm of both sides:
(2x+3)*log 5 = log 84
Solving for 2x+3, we get log 84 - log 5, and so
2x = -3 + log 84 - log 5. Dividing both sides by -3, we obtain the final answer:
-3 + log 84 - log 5
x = -----------------------------
