To find the inverse of a function switch the place of y (aka f(x) ) with x. Then solve for y.
Original equation:
y = 2x + 17
Switched:
x = 2y + 17
Solve for y by isolating it:
x - 17 = 2y + 17 - 17
x - 17 = 2y
(x - 17)/2 = 2y/2

Answer:
l(l - 2) = 168
Step-by-step explanation:
Let w = width
Let l = length
Let A = area
w = l - 2
A = l * w
also, A = 168
equating the two values of A
l * w = 168
l * (l - 2) = 168
l^2 - 2l = 168
l(l - 2) = 168
This is a binomial distribution where 80% of flights arrive on time (p = 0.8) and 20% do not (q = 1 - 0.8 = 0.2). Then the probability that exactly 2 flights arrive late follows the formula:
(nCr)(p^r)(q^(n-r)), where n = 16 (total # of flights), r = 14 (flights that arrive on time)
(16C14)(0.8^14)(0.2^2) = 0.2111
Add like terms. Ignore parenthesis. And change the negative in front of the 2 into a positive. 4y minus y and 3 plus 2 makes... 3y+5
