NCr/nPr=r!<br><br> give proof.

Sergio [31]

<span>It's 1/r!

nCr = n! / r!(n-r)!
nPr = n! / (n-r)!

If you divide the two you'd have:

n! / r! (n-r)! * (n-r)! / n! = 1/r!

Find the inequality represented by the graph?

Anon25 [30]

Answer:

$y \geqslant - 2x - 5$

Step-by-step explanation:

Since the shaded area is above the line and the line is solid, you will use the greater-than-or-equal-to sign.

Not to mention inequalities still have a slope and y-intercept. (In this case, the y-intercept will be -5, since the line crosses the y-axis at that point, and the slope will be -2 because the line is going down 2 units and to the right 1 unit.)

Hope this helps :)
