Answer:

250

Step-by-step explanation:

when x = 1, y = 250. That's the y-intercept

Answer: 200

Step-by-step explanation:

A y-intercept happens when x is 0. In this case, x represents the number of months, so we want to know how many stamps Carly has before starting. You can see that there is a pattern: every month, the number of stamps increases by 50.

For example, from month 1-3 (2 months), it increased 100, meaning it increased 50 per month

Now that we have that information, we have to go backwards.

At 1 month, it was 250, so at 0 months (where x = 0) it has to be 250-50, which equals 200.

Therefore, the answer is 200.

Hope this helps! :)

By [n][n] we denote the set {1,…,n}. A function f:[m]→[n] is called monotone if f(i) \leq f(j)f(i)≤f(j)whenever i < ji

Dafna11 [192]

Answer:

There are a total of ${ 6 \choose 3} = 20$ functions.

Step-by-step explanation:

In order to define an injective monotone function from [3] to [6] we need to select 3 different values fromm {1,2,3,4,5,6} and assign the smallest one of them to 1, asign the intermediate value to 2 and the largest value to 3. That way the function is monotone and it satisfies what the problem asks.

The total way of selecting injective monotone functions is, therefore, the total amount of ways to pick 3 elements from a set of 6. That number is the combinatorial number of 6 with 3, in other words

${6 \choose 3} = \frac{6!}{3!(6-3)!} = \frac{720}{6*6} = \frac{720}{36} = 20$

3x + x - 13 + 4x =12

GREYUIT [131]

3x + x - 13 + 4 - 6x =12

Combine like terms....

- 2x - 9 =12

Add 9 to both sides....

-2x = 21

Divide both sides by -2 to get x by its self....

x = -21/2
