Which of the following is the inverse of the function given below? f(x) = x + 2/7 a. q(x) = -x+2/7 b. r(x) = 7/x+2 c. p(x) = 7x -2 d. s(x) = 2x +7

Step-by-step explanation:

We  have been given the function

Let f(x)=y

Taking LCM we get

After rearranging the terms we will find the value of x in terms of y.

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.
