Why is 2x cubed different from 2x times 2x times 2x?
2X * 2X * 2X = 8X^3 2X^3 is saying 2*( X * X * X) = 2X^3
What is negative x plus 3x?
The expression "negative x plus 3x" can be simplified by combining like terms. Negative x can be written as -1x, so the expression becomes -1x + 3x. When you combine -1x and 3x, you get 2x. Therefore, the simplified expression is 2x.
2 times x?
we write 2 times x as 2x so if x=2, 2x=2(2)=4
What is x time x?
x times x = x2 (it's like 6 times 6. it would be 62. not 6 times 2. 2x means x times 2)
What is x x 2x?
2x+x is 3x
Why is 2x cubed different from 2x times 2x times 2x?
2X * 2X * 2X = 8X^3 2X^3 is saying 2*( X * X * X) = 2X^3
Does a negative plus a negative equal a positive?
a negative number plus a negative number is negative. here is a proof.(-x)+(-x)(-1)x+(-1)x-1(x+x)-1(2x)-2xa negative number times a negative number is positive though.
What two times the sum of some number increased by 7 is negative one?
2(x +7) = -1 2x + 14 = - 1 2x = -15 x = -7.5
What is the slope for y equals 1over2x?
y = 1/2x y = 1/2 times x to the negative 1 ( 1/2 x^-1) The slope is from differential calculus: slope = dy/dx = -1/2 times x to the negative 2 = -1/2x^2
What is the vertical asymptote of X minus 7 divided by negative 2X plus 7 times 2X plus 5?
f(x)= (x-7) /(-2x+7)(2x+5) set -2x+7=0 -2x=-7 x=7/2 set 2x+5=0 2x=-5 x=-5/2 x=7/2 and x=-5/2 are vertical asymptotes.
What are the factors of 2X squared minus negative X minus 10?
"minus negative x" means "plus x" (2x - 5)(x + 2) or (2x + 5)(x - 2) depending on what you really meant...
Does x times x equal 2x?
No, x + x equals 2x. x times x equals x2. (x times x equals x squared.)
What is x times -2?
X * - 2= - 2X========that simple
Is x a factor of 2x?
