x+2y=8

The x-intercept is the value of x when y=0, therefore substitute y=0 into the equation:

x+0=8

therefore, x=8

The coordinates of this point is (8,0)

2x-17=13 2x=30

x=15

One pair must be. If the other pair is also parallel it becomes a parallelogram.

((-3)cos(y))(x2)

Well first of all you need decide what rule you should use. Now, because they're multiplied together I'm going to use the product rule which is -

(dy/dx)= f'g +fg'

remember to write everything out -

f=((-3)cos(y))

f'=((3)sin(y))

g=x2

g'=2x

so from here it's pretty simple, you just sub in the values you have for each letter, remember to use brackets!

so....(dy/dx)= ((3)sin(y))(x2)+((-3cos(y))(2x)

Now you just need to simplify and gather like terms -

(dy/dx)=3x2siny-6xcosy

=3x(xsiny-cosy)

And there you have it!

Remember to check this yourself cause its been a while since I've studied this so I might have made a silly mistake somewhere. ^_^ Hope this helps!

6 12 18 24, etc. if you need both, 2, 4, 6 8 10, or 3, 6, 9, 12, if you need only one.

2x + 3 = -9
2x = -12
x = -6

a + 12=22
now you subtract by 12 because that's the number nearest a variable then u get a=10.

Yes

∫ coth(x) dx = ln(sinh(x))+ C

C is the constant of integration.

3y + 4-26 = 0

y = 7.333

(3+12) /5--------apex answer(:

(5x+3)(x+1)

X = -3/5 or x= -1

Because the NH3 molecules have to travel through the nitrogen and oxygen molecules in the atmosphere.

That is not an equation, since it doesn't have an equal sign.

it has 19 sides (:

lets say x equals 9

(9+4)*4*4*4*4=
13*4*4*4*4=
52*4*4*4=
208*4*4=
832*4=
3328 there. Easy!

Whoever told you otherwise was wrong. One cubic meter equals 1,000,000 cubic comtimeters.

X=-35

YES

It depends on the length. The surface area would be 4*length+8*length+16.

9 can get first. Then the remaining 8 can get second. 7 can get third. 6 can get fourth. 9*8*7*6=3,024.

There is really nothing infinite in real life. But there are several cases where for practical purposes, "infinity" is almost the same as "very large". One example is in optics, where it is not so much the distance from the lens to the object that matters, but the RECIPROCAL of the distance. In this distance, since the reciprocal of a very large number is close to zero, a far-away object (e.g., the Sun) can be approximated as "infinitely far away".

When x = 3, y = 3*32 - 2*3 = 27 - 6 = 21

It is not clear whether the spaces that appear between some xy pairs are intentional or whether they should have had some other symbols.

Ignoring those spaces, 21xy + 28.
