kupik [55]

Hello!

this problem comes with a slightly complex math equation that I had to ask my math teacher about, so I hope it helps.

<span>The expression n! means "the product of the integers from 1 to n"
</span>this can be said for any variable

say n is the total and r is the 2-letter combo

C(n,r<span>)=13!/</span>(2!(13−2)!)

If you use this equation, you will get a final answer of: 78

I hope this helps, and have a nice day.

Find the equation of the line through the point (–2, –2) that is perpendicular to the line y = 2x – 1.

lawyer [7]

Hi student, let me help you out!

.....................................................................................................

---------------------------------------------

Perpendicular lines have slopes that are <u>opposite inverses </u>of each other.

The opposite inverse of 2 is $\mathrm{-\cfrac{1}{2}}$ .

Now let's stick in this number into the equation $\mathrm{y=mx+b}$ :

$\mathrm{y=-\cfrac{1}{2}x+b}$ . Let's carry out several operations to determine the y intercept.

First, let's stick in -2 for x and y (Do you remember that the line passes through (-2,-2)? We're given that piece of information.)

$\mathrm{-2=-\cfrac{1}{2}\times(-2)+b}$ .

You are probably thinking, "Why did you do that and just complicate things?" Wait for it! ^-^

Upon simplifying this, we obtain: $\mathrm{-2=1+b}$ . See, it's nice and smooth now.

One last operation remains. We need to subtract 1 from both sides: $\mathrm{-3=b}$ .

∴, the equation of the line is: $\mathrm{\underline{\boxed{y=-\cfrac{1}{2}-3}}}$

Hope this helped you out, ask in comments if any queries arise.

Best Regards!
