Thank you all for replying! 

a = -9, b = 14,

or a = 14, b = -9,

but either way, a+b= 5

FTFY:

What is the slope of the line determined by any two solutions to the equation $\frac{2}{x}+\frac{3}{y} = 0$ ?

Express your answer as a common fraction.

If $x^2 = 16$, then the possible values of x are $\pm 4$, meaning 4 and -4.

$4+-4=0$, so the sum of all possible values of x are 0. 

Let x=minutes.

5x=10.

so, 25x= 50.

50 holes.

There are 3×2×1 = 6 ways to rearrange the A's and 2×1 = 2 ways to rearrange the N's.

So, there are: 720/(6×2) = 720/12 = 60 ways to rearrange all the letters in BANANA. 

x= - y/3

y= -3x

Since you don't define what x and y are, we don't know what the actual number is.

Not math but ok....

The same problem happened for me. It also happens for the problems that you post. I posted a problem that I was stuck on, and a few hours later, it disappeared and when I checked on my profile, it said that the problem is invisible for users.

If you mean x as a variable, then 6x 1/2=6x/2=3x

If you mean x as a multiplication symbol, then 6 X 1/ 2= 6/2= 3

Principal  + Simple Interest  = 

10000 +  10000 ( interest rate) ( time in years)  =

10000  + 10000(.10)(5)  =

10000 + 5000 =

$15000  after five years

Umm... There is no diagram...

Let's solve your equation step-by-step.

x^2−5x−12=0

For this equation: a=1, b=-5, c=-12

1x^2+(−5x)+(−12)=0

Step 1: Use quadratic formula with a=1, b=-5, c=-12.

x=−b±√b^2−4ac / 2a

x= −(−5)±√(−5)2−4(1)(−12) / 2(1)

x= 5±√73 / 2

so, 

x=5/2+ 1/2 √73 

or

 x= 5/2 + (−1)/2 √73

the / symbol means that it is a fraction.

You mean as in solving for x, right?

@Guest, please change your attitude. If you are asking for a question, then please ask for the answer politely.

I was willing to solve the problem for you, but your attitude just makes me not want to. 

The middle number is -3 and the last number is -10.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get -3

Multiply together to get -10

Can you think of the two numbers?

Try 2 and -5:

2+-5 = -3

2*-5 = -10

Fill in the blanks in
(x+_)(x+_)
with 2 and -5 to get...

(x+2)(x-5)

Answer: (x+2)(x-5)
