Range f (x)=3x-12. Domain is (-2,2)

1 answer:

6 0

Interpretation of question: Find the range, given the f(x) = 3x - 12 and the domain is from (-2,2).

Since the function is linear, it will always be increasing from left to right.

We can get the lower and upper bounds of our function's range by plugging in the lower and upper bounds of the domain into the function.

1) Plug -2 into the function.
3(-2) - 12 = -18

2) Plug 2 into the function.
3(2) - 12 = -6

The range is (-18, -6).

Evaluate Combination (6,6)

andrew11 [14]

Answer:

$nCx = \frac{n!}{x! (n-x)!}$

On this case n =6 and x =6 we got:

$6C6 = \frac{6!}{6! (6-6)!} = \frac{6!}{6! 0!}= \frac{6!}{6!}=1$

Step-by-step explanation:

The utility for the combination formula is in order to find the number of ways to order a set of elements

For this case we want to find the following expression:

$6C6$

And the general formula for combination is given by:

$nCx = \frac{n!}{x! (n-x)!}$

On this case n =6 and x =6 we got:

$6C6 = \frac{6!}{6! (6-6)!} = \frac{6!}{6! 0!}= \frac{6!}{6!}=1$

Possible my last brainliest if its right question idk may be more but this one is harsh for me

Correct Solution: He read 1.5 pages per minute.

Error Analysis: You should’ve divided 3 by 2 not 300. There are 300 pages in the book total. This information is irrelevant to the question. Cole reads 3 pages in two minutes. So you divide 3 by to to find out how many pages he reads per minute. 3/2=1.5
