How do you prove 2x powk plus 4x powk minus 1 equals x powk plus 1?
if you mean: 2x^k + 4x^k -1 = x^k +1
6x^k - x^k = 1 + 1
5x^k = 2
x^k = 2/5 cannot be solved further without more info.
with 2 variables you must have 2 equations to solve further.
What is the value of x if 3x - 4 equals x - 6?
3X - 4 = X - 6
subtract an X from both sides
2X - 4 = - 6
add 4 to each side
2X = - 2
divide each side by 2
X = - 1
--------------
check in original equation
3(-1) - 4 = (-1) - 6
- 3 - 4 = - 1 - 6
- 7 = - 7
checks
n is 2.
To solve, do the division:
. . . . . . . . .x2 +. 3x + (6-2n)
. . . --------------------------
x-2 | x3 + x2 - 2nx + n2
. . . . .x3 -2x2
. . . . .--------
. . . . . . . .3x2 - 2nx
. . . . . . . .3x2 - . 6x
. . . . . . . .----------
. . . . . . . . . (6-2n)x + n2
. . . . . . . . . (6-2n)x - 2(6-2n)
. . . . . . . . . ----------------------
. . . . . . . . . . . . . . . .n2 + 2(6-2n)
But this remainder is known to be 8, so:
n2 + 2(6-2n) = 8
⇒ n2 - 4n + 4 = 0
⇒ (n - 2)2 = 0
⇒ n = 2
-2x-6= -2x-6
Another answer:
-2x-6 = 2x+6
-2x-2x = 6+6
-4x = 12
x = -3
How do you drive the equation y equals mx?
y = mx
dy/dx = m
The derivative is simply the constant in front of x. Here, we have indicated that to be m.
What is the formula for finding the surface area of the circle?
A circle doesn't have a surface area because it is a 2D object. The area of a circle is = pi r2. if you mean the surface area of a sphere it is = 4 pi r2
What is the horizantal line test and vertical line test?
Horizonatal line test is a test use to determine if a function is one-to-one. If a horizontal line intersects a function's graph more than once, then the function is not one-to-one.
A one-to-one function is a function where every element of the range correspons to exactly one element of the domain.
Vertical line test is a test used to determine if a function is a function or relation. If you can put a vertical line through graph and it only hits the graph once, then it is a function. If it hits more than once, then it is a relation.
You feel someone near you all the time when no one is present?
I was born with a 6th sense,( believe me it isn't a great gift sometimes) , but it may be that you are picking up on a outer plain, again it may be your gardian angel, have you been going through some hard times?, if so that may be it.
What is the derivative of a half to the power of x?
(1/2)x = 2-x = exp (ln 2-x) = exp( -x ln 2). Since d/dx exp(x) = exp(x), we can use the chain rule to find that:
d/dx (1/2)x = -(ln 2) exp(-x ln 2).
Does 12 plus 20 equals 10 equal to 4x plus 14 equals 2x 30?
I am having difficulty understanding your question. 12 + 20 = 10 is obviously false (12 + 20 = 32).
If 4x + 14 = 2x + 30, then x must equal 8.
