A gallery has 25 paintings in its permanent collection, with display space for 10 at one time. How many different collections ca
Anastaziya [24]
You need to know in how many ways you can choose 10 out of 25 items when order does not matter. This is a combination problem.

_{n}C_{r} =  \dfrac{n!}{(n - r)!r!}

_{25}C_{10} =  \dfrac{25!}{(25 - 10)!10!}

_{25}C_{10} =  \dfrac{25 \times 24 \times 23 \times 22 \times 21 \times 20 \times 19 \times 18 \times 17 \times 16 \times 15!}{15! \times 10 \times 9 \times 8 \times 7 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1}

_{25}C_{10} =  \dfrac{25 \times 24 \times 23 \times 22 \times 21 
\times 20 \times 19 \times 18 \times 17 \times 16}{10 \times 9 \times 8 \times 7 \times 6 \times 5 \times 4 \times 3 
\times 2 \times 1}

_{25}C_{10} =  \dfrac{23 \times 11 \times 20 \times 19 \times 2 \times 17}{1}

_{25}C_{10} = 23 \times 11 \times 20 \times 19 \times 2 \times 17

_{25}C_{10} = 3,268,760

If c is a positive integer, how does the graph of y=x+c compare to the graph of y=x?
Len [333]

Answer:

It is shifted c units to the left  .

Step-by-step explanation:

In general, adding a constant c to the value of x shifts a graph c units to the left.

The graph of y = x + c is parallel to y = x,  the y-intercept becomes (0, c) and the x-intercept becomes (-c, 0).

In the diagram below, the red line is the graph of y = x, and the blue line is the graph of y = x + 1.
