Answer:
g(x)= (1/6)x+5/6 is the inverse function of f(x)
Step-by-step explanation:
We have y= 6x-5
Then, we take x depending on y like:
6x-5=y
6x-5 +5 = y + 5
6x= y+5
6x/6=y/6 + 5/6
x= y/6+ 5/6
Now, we replace x by the function g(x) and y by the variable x, then we have
g(x)= (1/6)x+5/6 is the inverse function of f(x).
Hope that you understand.
Answer:
7, 1, -7, -1.
Step-by-step explanation:
5+1/2(14b-8) = -6
5 + 7b - 4 = -6
7b + 1 = -6
7b = -7
b = -1
So, your answer will be 7, 1, -7, -1.
Hope this helps!
Answer:
0.8
Step-by-step explanation:
Find the mean of the list:
(0.2, 0.21, 0.17, 3.22, 0.2)
The mean of a list of numbers is given by:
(sum of elements)/(number of elements)
(sum of elements) = 0.2 + 0.21 + 0.17 + 3.22 + 0.2:
(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/(number of elements)
Counting, we see that the list has 5 elements:
(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/5
0.2 + 0.21 + 0.17 + 3.22 + 0.2 = 4:
4/5
4/5 = 0.8:
