Find the derivative: 9x^3 + 4x^2 +5x -10
To find the derivative of this equation, you have to remember that each term is a power function. For example: the equation ax^b will mean that the derivative is b*ax^(b-1) So we will have to do this for each term Note that the derivative of any constant is 0. So the derivative of -10 is 0 so the answer will be 27x^2 + 8x+5
Solve for x 9x+3 = 11x-10
To solve the question we first of all collect like terms. So we want all the x's on one side of the equal sign and we want the numbers on the other side. To take 11x to the left side of the equality sign we subtract 11x on both sides. 9x-11x+3 = 11x-11x-10. to get 9x - 11x + 3 = -10 Then we subtract 3 Fromm both sides 9x - 11x + 3-3 = -10 -3 To get. 9x - 11x = -10 -3 Then we solve the equation -2x = -13 We was the x to be by itself so we divide -2 on both sides (-2x)/-2 = -13/-2 to get x = 13/2 So the final answer is x = 13/2
