One solution.

y=mx+b

m=slope

b=y intercept

y=2x+4

the slope is 2

y intercept is 4

None because without an equal sign it's not an equation

There is none because its not an equation but some kind of algebraic expression.

2x^2-77x+119

It is not factorable if you are looking for integral factors (whole numbers). You might be able to use the quadratic formula if you wish to solve for the zeros (x-intercepts) of it.

If y = sin(cos(tan(x)))

Using the chain rule: (f(g(x)))' = f'(g(x)).g'(x)

Then dy/dx = cos(cos(tan(x))).-sin(tan(x)).sec2(x)

= -cos(cos(tan(x))).sin(tan(x)).sec2(x)

Unfortunately I don't think this can be simplified much more.

the answer is

No, never !

Any regular shape,like a cube or sphere, can be described mathematically and its volume can be calculated easily. An irregular shape, such as a rock can be mesured by displacment of water, or by scanning it in three dimensions.If the object's density is known, it need only be weighed.

volume is a amount of mater space takes up TY! PEOPLE!

Usually the easiest way to solve this kind of problem is to find two numbers whose sum is equal to the coefficient of the middle term, and whose product is equal to the product of the coefficients of the first and last terms. So in this case, we would want a product of 40, and a sum of -13. The only numbers that meet that condition are -8 and -5, so we'll use those, breaking the middle term down into two separate terms:

2x2 - 13x + 20 = 0

∴ 2x2 - 8x - 5x + 20 = 0

Now you can take a common factor out of both the first two terms and the last two terms, and group the like terms together, resulting in the answer you seek:

∴ 2x(x - 4) - 5(x - 4) = 0

∴ (2x - 5)(x - 4) = 0

∴ x ∈ {2.5, 4}

The intervals are determined by when the derivative is positive or negative, because the derivative is the slope and a negative slope means the function is decreasing. The function y=(x/sqrt(x2))+1, however, can be rewritten as y=x/absolutevalue(x) + 1, and as such will be represented as a pair of parallel lines, y=0 for x<0 and y=2 for x>0. As the lines are horizontal, the function is never increasing or decreasing.

7x+7=28x

28x-7x=7

21x=7

x=3

y = x - 3

The graph is a straight line, passing through the point [ y = -3 ] on the y-axis,
and having a slope of [ 1 ].

y=3

X^4 divided by Y^2

-6

-5y +2x = -10

-5y = -2x -10

y = 2/5x +2

So the slope = 2/5 and the y intercept = 2

it doesn't

(2, 3)

yes

15 multiplied by 9 is 135.
