Use substitution to solve the system of equations. If the system does not have one solution tell whether it has infinitely many solutions or no solution. Y = 2x + 1. 2y = 4x +2. Step 1 - Choose a variable to solve for. Look for the easiest way to solve the problem. Because the first equation is already solved for y I will choose the first equation.

The quadratic equation . has solutions . To use the quadratic formula, we first write equation (i) in the form. Here, a = 0.07, b = 4, c = −70, giving. The negative solution would be in the past. So, we only accept the positive. solution, t = 14.047 years = 14 years, 0.56 month. The Position Function (Model) of a Particle Moving Vertically:

(b) Solve this equation by first distributing the multiplication by 4. (a) Solve this equation by reversing what has been done to x. (b) Solve the equation for x. Check to make sure the original equation has a true value for the x you find. (a) By using the distributive property, write equivalent expressions for both sides of the equation.

Equation [42] defines a transcendental equation similar to that in equation [10] which required sin(λxmax) = 0. That equation has a simple solution since we know that the sin(nπ) = 0 when n is an integer. We do not have such a simple result for the equation that J0(λR) = 0.

The solution for v(x,t) which satisfies the diffusion equation with zero boundary conditions has already been found; it is given by equation [12]. [12] The coefficients Cn are found by the following formula for eigenfunction expansion coefficients. This is the same formula as equation [15] with f(x) replaced by f(x) – …
