2x-3y-7y+4x-5=6x-10y-5=6*10-10*4-5=60-40-5=60-45=15

It can be anything.

Example: x=1

10x3 + 3x2

8p+2=4p-10

8p-4p=-2-10

4p=-12

p=-12/4

=-3

x = 1.088348752

-8

x=0

normally an equation with the x value squared there would be two roots.

the two roots are positive 1 and postitive 1. since they are they same number there is actually only one root.

Yes, that's a shortcut often used for powers of functions.

Please note that for the special case of function to the power minus 1 of x there is a different definition - it is usually taken to mean the inverse function. So, if you want to write the reciprocal of a function, you have to express it in a different way.

In order to understand why everything to the zeroth power equal one, let's do some examples.

8^0

= 8^(1-1)

= (8^1)(8^-1)

= (8)(1/8)

= 8/8

= 1

2^0

= 2^(2-2)

= (2^2)(2^-2)

= (4)(1/2^2)

= (4)(1/4)

= 4/4

= 1

(x + 1)^0

= (x + 1)^(1-1)

= [(x + 1)^1][(x + 1)^-1]

= (x+ 1)[1/(x + 1)]

= (x + 1)/(x + 1)

= 1

It is cosh(x) + c where c is a constant of integration.

V = d / t (or v = dd/dt & v = integral of acceleration with respect to time for physics involving calculus)

where V is velocity, d is displacement (distance traveled) and t is time.

vf = vi + a*t

(vf)^2 = (vi)^2 + 2*a*d

Where vf is final velocity, vi is initial velocity, and a is acceleration

v = p/m

Where p is object's momentum and m is object's mass

90 degrees is the maximum velocity for diesel. Diesel is generally any liquid fuel used in diesel engines within vehicles.

Surface area = 2*(8*5 + 5*2.5 + 2.5*8) = 2*(40 + 12.5 + 20) = 2*72.5 = 145 square units.

All that is visible is an expression. An expression cannot be solved.

Let's solve this by substitution. We're told:

3x + y = 9

6x = 4 - 2y

Let's start with the second equation, and solve for y:

6x = 4 - 2y

3x = 2 - y

2 - 3x = y

Now we can substitute it into the first equation, replacing all occurrences of y with 2 - 3x:

3x + (2 - 3x) = 9

2 = 9

Ah! That of course makes no sense, which tells us that the lines do not intersect at all, but are in fact parallel to each other. Let's confirm that by rearranging each of them into standard form:

3x + y = 9

y = 9 - 3x

y = -3x + 9

6x = 4 - 2y

y = 2 - 3x

y = -3x + 7

So there you have it. Those expressions describe two lines that have a slope of 3 and a y position that differs by 2.

-0.25x=50.55

which is x=-202.2

No, it is not a direct variation.
