Can someone please check my answers below for accurateness? The instructions are: Differentiate and simplify. 1) y=(2x^2+3x-1)(3x^2-5x-3) y'=(4x+3)(3x^2-5x-3)+(2x^2+3x-1)(6x-5) 2) y=(5x^2+3x-1)(3x^2-5x-3)
-7+ 5x = 10x-2? im not sure I know its -1, but im not sure how. -7 + 5x = 10x - 2 Since we need to get the unknowns on one side and the knowns on the other side and change their signs: 5x - 10x = 7 - 2 -5x = 5 x = -1 wait how did

1) What is the value of 19 + 5a^4 + 3b^2 when a = 2 and b = -4? (this is not a multiple choice question) but my answer is 147. 2)Combine the like terms to simplify the expression: 4 + 7xy^2 + 5y^3 + 10x -4xy^2 - 8x - 4y^3 + 9 -
I have a take home test and I'm stuck on a couple. Anyone help please? 1. Find the vertex & axis of symmetry: -5(x+4)^2-4 2. Find the vertex & axis of symmetry: y=x^2-10x+3 3. Simplify: (2i+5)(3+4i) 4. Simplify: 3(21+2i)+(4-5i) 5.
Find the equation of the tangent line 5x^2+y^2=14 at (1,3). P.S: It's calculus. So far I know this much 10x+2y(dy/dx)=o -10x -10x ___________________ 2y(dy/dx)= -10x (dy/dx)= -10x/2y= -5x/y m= -5(1)/3= -5/3 y=mx+b 3= -5/3(1)+b
i was wondering if anyone could help me on this problem. expand: x^-2 (y^2 + 10x) z^3 (5x + 3z^-4) First one: x^-2 (y^2 + 10x) x^-2 is the same thing as 1/x^2. Therefore, we have this: 1/x^2 (y^2 + 10x) Multiply using the
