x²+y²=25; y-3x=13; x²+(13+3x)²=25; x²+9x²+78x+169=25; 10x²+78x+144=0; 5x²+39x+72=0; (5x+24)(x+3)=0; x=-24/5 and y=-7...

dy/dx=(dy/dt)*(dt/dx); dy/dt=3+16t^-3; dx/dt=3(t-1)²; dt/dx=1/3(t-1)²; dy/dx=(3+16t^-3)/3(t-1)²

x³ - 6x² + 11x - 6 = 0
Let (x-a)(x-b)(x-c) = x³ - 6x² + 11x - 6=> abc = -6 and a + b + c = -6 From abc=-6, find the possibilities of their values: (1,2,...

Balancing equations is a simple conservation of the elements in a reaction: what you start with is what you finish with. With that in mind, let's take a look at the equation:C₂H₄ + O...

Electromotive Force (EMF) is the measure of how much energy a source like a battery gives to the charges in a circuit. As with most things, this energy source is not 100% efficient, and has an associated ...
