Answer:
Step-by-step explanation:
**This is a non-linear function and therefore <u>does not have a constant rate of change</u>. It will have a different slope depending on what points you use in the average rate of change formula:
To calculate rate of change, differentiate.
substitute y for :
Take natural logs of both sides:
Apply the log rule :
Differentiate with respect to :
Mulitply both sides by :
Replace with
Therefore, rate of change of the function is :
Answer:
(1.25, - 5 )
Step-by-step explanation:
Given the 2 equations
- 4x + 3y = - 20 → (1)
4x + 2y = - 5 → (2)
Adding the 2 equations term by term will eliminate the x- term
5y = - 25 ( divide both sides by 5 )
y = - 5
Substitute y = - 5 into either of the 2 equations and solve for x
Substituting into (2)
4x + 2(- 5) = - 5, that is
4x - 10 = - 5 ( add 10 to both sides )
4x = 5 ( divide both sides by 4 )
x = = 1.25
Solution is (1.25, - 5 )
Answer:
Step-by-step explanation:
put them both in exponential form and then since they are both base 6, you can add the exponents.
