Answer:

Juan did.

Step-by-step explanation:

the two fastest speeds are 26.47 and 26.9 seconds. In order to be able to properly work with that, you need to add a 0 to 26.9 so that it turns into 26.47 and 26.90 seconds. If you were yo subtract those, you would have:

26.90-26.47= 0.43

Therefore, 26.47 seconds is faster than 26.9 seconds.

Answer: Kyrah ran the fastest

Step-by-step explanation:

The other answers are wrong because remember these people were being timed so the bigger there number was the longer they took to make it, the smaller there number was the fastest they ran.

Which of the following pairs of functions are inverses of each other?
AnnyKZ [126]

Answer:

Step-by-step explanation:

Rearrange each function to solve for x.

Switch x and y,

The resulting equation is the inverse function.

A:

f(x) = y = 5+x

x = y-5

y = x-5

f⁻¹(x) = x-5

g(x) = 5-x ≠ f⁻¹(x)

g(x) is not the inverse of f(x).

:::::

B:

f(x) = y = 2x-9

x = (y+9)/2

y = (x+9)/2

f⁻¹(x) = (x+9)/2

g(x) = (x+9)/2 = f⁻¹(x)

g(x) is the inverse of f(x).

:::::

C:

f(x) = y = 2/x - 6

x = 2/(y+6)

y = 2/(x+6)

f⁻¹(x) = 2/(x+6)

g(x) = (x+6)/2 ≠ f⁻¹(x)

:::::

D:

f(x) = y = x/3 + 4

x = 3y - 12

y = 3x - 12

f⁻¹(x) = 3x - 12

g(x) = 3x - 4 ≠ f⁻¹(x)

g(x) is not the inverse of f(x).

What is 2x + 2x + 2y + 2y?
marin [14]

Answer:

4x+4y

Step-by-step explanation:

Only like terms can be added together so the numbers with the variable x are added together and numbers with the variable y are added together.

The expression can no longer be simplified since it has no other ways to.
