3x y 20 2x+y8. Answer (1 of 8) dy/dx = 12x^3 4x 0 d/dx of y is dy/dx d/dx of 3x^4 is, according to the power rule, 12x^3 The power rule dictates that one simply drops the exponent and makes it a coefficient of the variable and then subtracts one from the exponent d/dx of x^n = nx^(n1) d/dx of 2x^.  3x – 2y 3z = 8 2x y – z = 1 4x – 3y 2z = 4 The system of equation is 3x – 2y 3z = 8 2x y – z = 1 4x – 3y 2z = 4 Writing equation as AX = B 8(3&−2&3@2&1&−1@4&−3&2) 8(𝑥@𝑦@𝑧) = 8(8@1@4) Hence A = 8(3&−2&3@2&1&−1@4&−3&2), 𝑥= 8(𝑥@𝑦@𝑧) & B = 8(8@1@4) Calculating A A = 8(3&−2&3@2&1&−1@4&−3&2) = 3 8(1&−1@−3&2) – 1( – 2). The system is now solved 2x3y=2,x2y=8 Put the equations in standard form and then use matrices to solve the system of equations \left(\begin{matrix}2&3\\1&2\end{matrix}\right)\left(\begin{matrix}x\\y\end{matrix}\right)=\left(\begin{matrix}2\\8\end{matrix}\right) Write the equations in matrix form.

So that's the point 0, 1 right there This is the yaxis, that is the xaxis And the slope is 3 That means if we move 1 in the positive xdirection, we're going to move up 3 in the positive ydirection So we move 1 in the xdirection, we move up 3 If we moved 2 in the xdirection, we would move up 6 Just like that Because 6 over 2 is still 3. Select a few x x values, and plug them into the equation to find the corresponding y y values The x x values should be selected around the vertex Tap for more steps Replace the variable x x with 0 0 in the expression f ( 0) = 2 ( 0) 2 − 3 ⋅ 0 − 2 f ( 0) = 2 ( 0) 2 3 ⋅ 0 2 Simplify the result. This equation is in standard form a x 2 b x c = 0 Substitute 3 for a, − 2 for b, and 2 − y for c in the quadratic formula, 2 a − b ± b 2 − 4 a c x=\frac {\left (2\right)±\sqrt {\left (2\right)^ {2}4\times 3\left (2y\right)}} {2\times 3} x = 2 × 3 − ( − 2) ± ( − 2) 2 − 4 × 3 ( 2 − y) Square 2.

For example the command 2x @ 3 evaluates the expression 2x for x=3, which is equal to 2*3 or 6 Algebra Calculator can also evaluate expressions that contain variables x and y To evaluate an expression containing x and y, enter the expression you want to evaluate, followed by the @ sign and an ordered pair containing your xvalue and yvalue.  Help a stranger please This is for my homework and I'm having a hard time solving these equations Show the complete solutions and final answers please It will be a great help Thank you so much This covers Additional Topics on Equations of Order One, Coefficient Linear in Two Variables 1 (6x3y2)dx(2xy1)dy=0 2 (x2y1)dx(2xy5)dy=0. 1 Problem 1 (2x3)(2y −2)y0 = 0 We want f x = M(x,y) = 2x3 and f y = N(x,y) = 2y−2 We check if this is possible M y = 0 N x = 0 Now antidifferentiate M with respect to x f(x,y) = Z M(x,y)dx = Z 2x3dx = x2 3xg(y) where g is some unknown function of y Two ways of proceeding (which are equivalent) I’ll list both methods for this.

Algebra Solve for y 2x3y=8 2x − 3y = 8 2 x 3 y = 8 Subtract 2x 2 x from both sides of the equation −3y = 8−2x 3 y = 8 2 x Divide each term by −3 3 and simplify Tap for more steps Divide each term in − 3 y = 8 − 2 x 3 y = 8 2 x by − 3 3. A curve C has the equation y2 – 3y = x3 8 (a) Find x y d d in terms of x and y (4) (b) Hence find the gradient of C at the point where y = 3 (3) (Total 7 marks) 5 A curve has equation 3x2 – y2 xy = 4 The points P and Q lie on the curve The gradient of the tangent to the curve is 3 8 at P and at Q (a) Use implicit differentiation to show that y – 2x = 0 at P and at Q (6). If 2x 2 3xy y 2 x 2y 8 = 0, then dy/dx is equal to If 2x 2 3xy y 2 x 2y 8 = 0, then dy/dx is equal to.

 2x y = 8 3x 2y = 5 Primero despejamos cualquier incógnita de la una ecuación, 2x y = 8 y = 2x 8 Ese valor lo remplazamos en la otra ecuación, 3x 2 (2x 8) = 5 3x 4x 16 = 5 7x = 21 x = 21/7 x = 3 Luego, buscamos el valor de Y, y = 2x 8 y = 2 (3) 8 y = 6 8 y = 2 Respuesta El valor de X es 3 y de Y es 2. The first constraint tells us that's what y is So negative 5x plus 8 is equal to negative 2 Now, we have one equation with one unknown We can just solve for x We have 10x plus So we can multiply it We can distribute this 2 onto both of these terms So we have 2 times negative 5x is negative 10x And then 2 times 8 is 16.
