What is the value of 2x3 plus 15y if x equals -7 and y equals 2?
If x = -7, then x3 = -343 so that 2x3 = -686 y = 2 then 15 y = 30 So 2x3 + 15y = -686 + 30 = -656
What is the value of 2x3 plus 15yif x equals -7 and y equals 2?
x = -7, y = 2 ⇒ 2x3 + 15y = 2 x (-7)3 + 15 x 2 = 2 x (-343) + 15 x 2 = -656
How do you factor 6x2 - 20x plus 2x3?
2x(x + 5)(x - 2)
What is the f dashed x or deriative of 1 over 2xcubed plus 5?
f'(x) = 1/(2x3 + 5) rewrite f'(x) = (2X3 + 5) -1 use the chain rule d/dx (2x3 + 5) - 1 -1 * (2x3 + 5)-2 * 6x2 - 6x2(2x3 + 5) -2 ==================I would leave like this rather than rewriting this
How do you factor this Y equals x³ plus 3x² - 10x-24 and Y equals -x³ -6x²-3x plus 10?
It can be simplified in the form of: 2x3+9x2-7x-34 = 0
X plus 1 divided by 2x cubed plus 3x plus 5?
(x + 1) / (2x3 + 3x + 5) --- Can't depict long division here, but you can work this out by seeing if (x + 1) is a factor of (2x3 + 3x + 5). If it is, then the answer will be 1/(the other factor). In this case, that is true. (2x3 + 3x + 5)/(x + 1) = 2x2 - 2x + 5, so the term term above is equal to: 1 / (2x2 - 2x + 5)
Solve 2x3 plus 5x-5?
2 x 3 = 65 x -5 = -256 + -25 = -19
