How do I know if the function is a linear function?

Lilit [14]

Answer:

This is not a linear function.

Step-by-step explanation:

It is a quadratic function. If you were to make a table of the x and y values of the function it would look like this:

x y

0 -4

1 -1

2 8

Just by looking at these three values, we can see that they do not increase at a consistent rate. It increases by 3 from 0 to 1, but increase by 9 from 1 to 2. You can tell if a function is linear by seeing if it increases at a constant rate. (In this case it does not)

Explain: how would you model 5 x 2/3

ELEN [110]

Well as you can see 5 x 2/3= 3 1/3 there is 7 steps to figure it out

1. set up the problem
5 x 2/3

2. put a 1 on 5 to make it a fraction
5/1 x 2/3

3. multiply and divide
(5 x 2) / (1/3)

4. find out the answer
10/3

5. turn the answer into a mixed fraction
10 divided by 3= 3.1 3 stays the same you don't need to say 1

6. it equals
3 1/3

7. so the answer is
3 1/3

Sammy has x flavors of candies with which to make goody bags for Frank's birthday party. Sammy tosses out y flavors, because he

harkovskaia [24]

Answer:

$^{(x-y)}C_{10}=\frac{(x-y)!}{10! \times (x-y-10)!}$

Step-by-step explanation:

Total flavors Sammy initially had = x

Number of flavors Sammy throw away = y

After throwing away y flavors, the number of flavors Sammy will be left with = x - y

He needs to make 10-flavor bags from these (x - y) flavors. In order words he needs to chose 10 flavors for each bag from(x - y) flavors. The order of selection is not important here, so this is a problem of combinations. Also since we have to make selections or small groups, this also indicates that we have to use combinations.

So we need to make combinations of 10 flavors from a total of (x - y) flavors. This can be represented as $^{(x-y)}C_{10}$

The formula for combinations is:

$^{n}C_{r}=\frac{n!}{r!(n-r)!}$

Using the values in this formula, we get:

$^{(x-y)}C_{10}=\frac{(x-y)!}{10! \times (x-y-10)!}$
