2X * 2X * 2X = 8X^3 2X^3 is saying 2*( X * X * X) = 2X^3
-x + 3x = 2x
we write 2 times x as 2x so if x=2, 2x=2(2)=4
x times x = x2 (it's like 6 times 6. it would be 62. not 6 times 2. 2x means x times 2)
2x+x is 3x
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.
2X * 2X * 2X = 8X^3 2X^3 is saying 2*( X * X * X) = 2X^3
1, 2, 5, 10, x, 2x, 5x, and 10x and the negative of each of those.
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
2(x +7) = -1 2x + 14 = - 1 2x = -15 x = -7.5
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.
"minus negative x" means "plus x" (2x - 5)(x + 2) or (2x + 5)(x - 2) depending on what you really meant...
No, x + x equals 2x. x times x equals x2. (x times x equals x squared.)
-x + 3x = 2x
Yes, 2x is 2 times x.
X * - 2= - 2X========that simple
(2x x 3x) x 2 = 12x (2x times 3x times 2)
