which of the following pairs of functions are inverses of each other​

Answers

Answer:

c would be the answer you are looking for and please mark brainliest

Step-by-step explanation:

Options A and D have functions that are inverses of each other.

What is an inverse function?

The inverse function is defined as a function obtained by reversing the given function.

To check whether two functions are inverses of each other, we need to check if the composition of the functions in both orders results in the input value.

Here, we need to check if f(g(x))=x and g(f(x))=x for all values of x in their domains.

A. f(x) = 7/(x-9) and g(x) = (x+9)/7

f(g(x)) = f((x+9)/7) = 7/((x+9)/7 - 9) = 7/(x/7) = x, so f and g are inverses of each other.

B. f(x) = x/6 + 8 and g(x) = 6x - 8

f(g(x)) = f(6x-8) = (6x-8)/6 + 8 = x/6 + 8/6 = x/6 + 4/3, which is not equal to x. Therefore, f and g are not inverses of each other.

C. f(x) = 2 + ∛x and g(x) = 2 - x³

f(g(x)) = f(2 - x³) = 2 + ∛(2 - x³) ≠ x, so f and g are not inverses of each other.

D. f(x) = 5x - 11 and g(x) = (x+11)/5

f(g(x)) = f((x+11)/5) = 5((x+11)/5) - 11 = x, and g(f(x)) = g(5x-11) = (5x-11+11)/5 = x/5, so f and g are inverses of each other.

Therefore, only options A and D have functions that are inverses of each other.

help. please. i have to type 20 things.

Answers

Answer:

Top Left: Acute Top Right: Acute Bottom Right: Obtuse Bottom Left: Right

Step-by-step explanation:

The top left and right have all angles less than 90 degrees which makes them acute. The Bottom right has an angle over 90 degrees which makes it obtuse, and the last one has a right angle 90 degrees.

there’s only 3 option but i’ll try my best. the top right is an acute triangle. bottom left is an obtuse triangle and bottom right is a right triangle. the top left one is an equilateral triangle but that isn’t an option. hope this helps :)

Reed is purchasing an X-Box One. He made an initial payment of $75 to the store, and will pay $15 each month until the system is paid off. Which equation represents the relationship between x, the number of monthly payments Reed has paid, and t, the total amount that Reed has paid the store?

A. t = 75x + 15 C. t = 15x + 75

B. t = 15x - 75 D. Not Here

Answers

C.) T=15x+75

its 15 dollars each month and since you don't know the number of months the variable would correspond with 15 and you just need to add 75 onto it

Answer:

C. t = 15x + 75

Step-by-step explanation:

since you already payed the 75 dollars you add it and you multiply 15 by x because x is the number of months you pay

Molly is painting her bedroom walls, and the paint costs $24 per gallon. How much does the paint cost per quart?
$3 per quart
$6 per quart
$48 per quart
$96 per quart

Answers

$6 per quart.

A quart is 1/4 of a gallon.

Answer:

$6 per quart

Step-by-step explanation:

Since we are trying to find out how much money a quart of paint will cost, we need to find out how many quarts are in one gallon.

There are 4 quarts in a gallon, therefore we take $24 divided by 4 and get $6 per quart.
