well think, 2 times what plus 8 = 12? well only one thing works ther : 2.  (2•2) +8 =12

5 divided by 3 is approximately 1.666

Well it's true, I was gonna ask you to help me with this I was gonna tell you something in return 

Looks that way?   

But why would a famous singer and actor be on a math website?

Her photo is if Madison Beer 

What happend

Hope you feel better las 

I agree Sweetnut.

sec θ  /  [ csc  θ  - cot  θ ]    -   sec  θ / [ csc  θ + cot  θ]       get a common denominator

[ sec  θ (csc  θ + cot  θ)  - sec  θ ( csc  θ - cot  θ ]  /  [  csc^2  θ - cot^2 θ ]

[ 2sec  θ cot  θ ]  / 1 

[ 2  ( 1 / cos θ) (cos θ / sin  θ) ]  

[ 2 /  sin  θ ]

2 csc  θ          and this  =  the right side

Go ahead you havent been on in months and ypu start drama no iffense lad

x^2+y^2+16x−24y+159=0   

x^2 + 16x  + y^2 - 24y   =  -159        complete the square on x and y

x^2 + 16x  +  64  + y^2 - 24y  + 144   =   -159 + 64 + 144        factor

(x  +  8)^2   + (y - 12)^2   =  49

The center is  ( -8, 12 )

Hopefully that helped.

(-3/-4) * -2

3/4 (-2)

3/4 * -2/1

-6/4

-3/2 or -1 1/2

p  = - 1/2......so   the equation is

4p(y-7.5)   = (x - 4)^2

-2(y - 7.5)  = (x - 4)^2    .........."C"   is correct

1/5 = -1/2x + 3/2

times both sides by 2 since on the right the common denominator is 2

2(1/5) = -1x + 3

2/5 = -1x + 3

then subtract both sides by three

2/5 = -1x + 3

-3              -3

or 

2/5 = -1x + 15/5

-15/5         -15/5

then simplify

-2 3/5 = -1x

or 

-13/5 = -1x

then divide both sides by -1

(-2 3/5)/-1 = -1x/-1

x = 2 3/5

or x = 13/5

 y=−16x^2+7x−80     factor  out -16

y  =  -16 (x^2  - 7/16 x + 5)   complete the square on x

y  =  -16 (  x^2   - 7/16 x  + 49/1024  +  5   -  49/1024 )

y  =  -16 [  (x - 7/32)^2  + 5071/1024 ]

y =  -16(x - 7/32)^2  - 5071/64

The vertex is   ( 7/32, -5071/64)

To find the focus....solve this......    1/4p  = -16   → p  = -4

So.....the focus is ( 7/32, -5327/64)

And the equation of the directrix  is      y  =  -5071/64  +  4  = -4815/64

Here's a graph  :  https://www.desmos.com/calculator/nhy4nlep4o

go away

-7x-7(-4+2x) = -37-8x   simplify

-7x + 28 - 14x   =   -37  - 8x

-21x + 28   =   -37   - 8x       add 37, 21x  to both sides

65  =  13x         divide both sides by 13

5  = x

Lol, One simply does not leave, you never left to begin with.

13 is bigger than 9

It is 70
