Answer:
y = (2/5)x + 2
Step-by-step explanation:
To find the inverse of a function, we simply exchange the variables x and y and solve for y.
For this function we will write it as such:
y = -5 + (5/2)x
So to find the inverse, we will swap the x and y and solve.
y = -5 + (5/2)x
x = -5 + (5/2)y
x + 5 = (5/2)y
(2/5) * (x + 5) = y
(2/5)x + (2/5)5 = y
(2/5)x + 2 = y
Thus the inverse of the function is:
y = (2/5)x + 2

this is gp because
because ratio of next term to previous term is always same.
8/16= 4/8 = 1/2
so common ratio is 1/2
first term is a = 16
so nth term of a gp is given as
Tn = ar^(n-1)
T10 = 16 × (1/2)^(10-1)
= 16 × (1/2)^9 = 1/32

Answer:
France = 15, Italy = 14, Korea = 13
Step-by-step explanation:
We are trying to find 3 consecutive integers whose sum is 42, then the highest integer will be France's gold medal count since they won the most, the second highest will be Italy, and the lowest integer will be Korea.
let n be the first/smallest integer, since they are consecutive, the next two integers are n+1 and n+2. Summing these, we get n + (n+1) + (n+2) = 42. Solve to get n = 13, n + 1 = 14, and n + 2 = 15
