You can put the fractions next to each other and multiply the numerator by the numerator, and the denominator by the denominator, like this:

                       (numerator) 2 x 3(numerator)

                    (denominator) 9 x 5(denominator)

2 x 3 = 6

9 x 5 = 45

Your resulting fraction would be 6/45

Yes, I agree, I mean some people actually need help with math problems, and they would really be annoyed if they got a reply saying "its 21" or something like that. Please, stop this is a math website, for actual math questions and people who can help, and if you want to say 21 go to insta or something, because that is a more apropriate place to say that kind of stuff.

Good luck...the 9 + 10, 1 + 1  type posts have been recurrent questions on here since I joined last March......just ignore them......

It's 10, please stop with the 9+10 jokes

Thanks!!!!

OMFG, IT'S 21!

Just evluate this

V = pi * (12)^2 * 9

say you have 9 circles then add 10 more circles and you get 19

256^(x+2)=16^(3x-1)

Notice that 256 =  2^8   and 16 = 2^4

So we have

2^8^(x + 2) = 2^4^(3x -1)   and dropping the equal bases and solving for the exponents, we have

8(x + 2) = 4(3x - 1)

8x + 16 = 12x - 4    add 4 to both sides and subtract 8x from both sides

20 = 4x    divide both sides by 4

5 = x

If you have 10 and a single digit number just add a one to that single digit number. 19

Spelling grammar that way is one of my bad habits and I usually forget how to spell it within a day. 

XDDDDD I <3 Irony!

was that on purpose?

Don't worry about it....I checked both of the points in your equation and it was all good....in fact, I kind of like your way better than the way I learned it...LOL!!!

I don't think he's going to be offended.... Besides, my grammer and spelling are both better than my math skills! 

that's hurtful...he can still see ur post u know that right?

Really? That's the only way I know how to solve those type of questions, how did you learn to do it?

That's an interesting technique, saseflower.....I don't think I've seen it done that way before.....very nice....!!!!

Wow generic Yea BJ and zegroes seem to have been gone for a while or something

Yep....taking out a common factor is a vital skill in being able to factor...glad you saw it...!!!

Put the points in slope form

m = (-4) - (-6)/(-2) - (-7)

Solve

m = 2/5

Now put the numbers in slope-intercept form, and pick one point (im doing (-2, -4))

-4 = 2/5(-2) + b

Multiply

-4 = -4/5 + b

add on both sides

-3 1/5 = b

Now plug m and b into the eqation again

y = 2/5x - 3 1/5
