  1. SOLUTION Begin with x 2 + xy + y 2 = 1. Differentiate both sides of the equation, getting D (x 2 + xy + y 2) = D (1),. 2x + (xy' + (1)y) + 2 y y' = 0,. so that (Now solve for y'.). xy' + 2 y y' = - 2x - y, (Factor out y'.). y' [ x + 2y] = - 2 x - y,. and the first derivative as a function of x and y is (Equation 1).
  2. Route 13 (Japanese: 13番道路 Route 13) is a route in northern Kalos, connecting Coumarine City and Lumiose City, and is the location of the Kalos Power contwinkevbderlogptanvidensauculmody.coinfo route is also known as Lumiose Badlands (Japanese: ミアレの 荒野 Miare Badlands).. In the badlands, wild Pokémon will appear in the form of dirt mounds that will chase the player and battle them when near, moving only when.
  3. Consider the following. x' = 12x – 13y y' = 13x – 12y, X(0) = (12, 13) (a) Find the general solution. (x(t), y(t)) = Determine whether there are periodic solutions. (If there are periodic solutions, enter the period. If not, enter NONE.) (b) Find the solution satisfying the given initial condition. (x(t), y.
  4. Find the 9th term in the expansion of (x-2y) Since we start counting with 0, the 9th term is actually going to be when k=8. That is, the power on the x will =5 and the power on the -2y will be 8. The coefficient is either C(13,8) or C(13,5), combinations are symmetric, so it doesn't matter.
  5. Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals. For math, science, nutrition, history.
  6. So everywhere we see an x, we can substitute it with a y minus 4. So let's do that. So if we substitute y minus 4 for x in this top equation, the top equation becomes 2y is equal to instead of an x, the second constraint tells us that x needs to be equal to y minus 4. So instead of an x, we'll write a y minus 4, and then we have a plus 7.
  7. x = 13 + 5y. Solve the equation for x. Multiply the numbers. Calculate the difference. The possible solution of the system is the ordered pair (x, y) (x, y) = (-2,-3)Check if the given ordered pair is the solution of the system of equation. Simplify the equalities. Since all of the equalities are true, the ordered pair is the solution.
  8. The two terms, 2(x – y) and –b(x – y), do indeed have a common factor; namely, the parenthetical factor x – y. This binomial may be different from what I'm used to seeing referred to as being a "factor", but the factorization process works just the same for this expression as it did for every other expression before.
