5x^2(4x - 5)(5x + 11)

No. A proportional relationship between "y" and "x" must be of the form:y = kx

where "k" can be any constant. Thus,

y = 16x

would work perfectly. However, the additional "+4" makes it impossible to convert it to this form.

b4-3b3-10b2=0

divided by b2 -> b2-3b-10=0 (if b is not 0)

Delta=(-3)x(-3) - 4 x 1 x -10 = 49

b=(3+7)/2 or b=(3-7)/2

b=5 or b =-2

if b=0 the equation also holds then b=0 or b=5 of b=-2

X=2

There are missing + or - symbols, but the square is completed in this case by dividing the coefficient of the x term by 2, giving:

(x ± 2)2 = x2 ±4x + 4

So to get to the original equation, there is needed an extra +1 or -9:

(x ± 2)2 +1 = x2 ±4x +5

(x ± 2)2 - 9 = x2 ±4x - 5

Depending upon what the missing (+-) symbols are. (Whatever the sign before the 4x, the same is used in the brackets of the square.)

When you can divide the Numerator and the Denominator by something other than 1 or itself

Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals" etc. Also use ^ to indicate powers (eg x-squared = x^2).

There is no symbol between x and 3.

The coefficient of x2 is -3 which is negative. Therefore the curve is downward opening.

That depends on where you are trying to log in. Usually it is done the same way as the 9 previous times.

But if the thing you are trying to log in for the tenth time has some sort of restricted access, it might require some hacking skills or a bypass. Unfortunately I cannot help you with that, especially not knowing where you are trying to log.

a number

Roman numerals can still be found on such things as... clocks and watches, sundials, old mile stones, the dates in the credits of movies, dates in books, sequals of movies (Jurassic Park III etc), the names of chemical compounds (such as Iron (II) chloride), the regnal numbers of kings and queens (Edward VI etc), and on some coins.

It is equal to 1024 kilobytes, or (1024 x 1024) bytes.

-4-3x=4-5

-1x=-1

x=-1/-1

x=1

x = 87 so 3x + 2 = 261 + 2 ie 263

x equals 7

Set y = 0: So 2x =a ie x = a/2. So the x-intercept is (a/2, 0)

Set x = 0: So 3y = a ie y = a/3. So the y intercept is (0, a/3)

8x6 + 24x5 + 16x4 = 8x4 ( x2 + 3x + 2) = 8x4 (x + 2) ( x + 1)

The two solutions are the conjugate complex numbers, +i*sqrt(11) and -i*sqrt(11), where i is the imaginary square root of -1.

Sinθ plus cosθ2 plus sinθ-cosθ2 equals 2 does not equal 2. It equals 2sinθ. The cosθ2 terms cancel out and you are left with sinθ + sinθ which is 2sinθ.

3/10. If you multiply by 10 yo divide by 10 to maintain the consistency.
