Y = x + 7
m1 = 1
m1 × m2 = - 1
1 × m2 = - 1
m2 = - 1
- 1 = - 1(-1) + c
- 1 = 1 + c
c = - 2
y = - x - 2
x + y = - 2
- x - y = 2
the answer is the 2nd one
The average value of f(x) over [2, 6] is given by the definite integral,
![\displaystyle f_{\rm ave[2,6]} = \frac1{6-2} \int_2^6 3\ln(2+x^3)\cos(x) \, dx](https://tex.z-dn.net/?f=%5Cdisplaystyle%20f_%7B%5Crm%20ave%5B2%2C6%5D%7D%20%3D%20%5Cfrac1%7B6-2%7D%20%5Cint_2%5E6%203%5Cln%282%2Bx%5E3%29%5Ccos%28x%29%20%5C%2C%20dx)
and is approximately -1.67284.

Answer:
y = lnx / ln 7.
Step-by-step explanation:
x = 7^y
Take logarithms of both sides:
ln x = ln 7^y
ln x = y ln 7 ( because ln a^b = b ln a. One of the Laws of Logarithms).
y = lnx / ln 7.
