Since the xintercept and yintercept of the line 2x 3y = 169 are (845,0) and (0,169/3) respectively Similarly, the xintercept and yintercept of the line 5x = y 74 are (148,0) and (0,74) respectively After plotting the line in the graph (shown below), we found that, the intersection point of the lines is (23, 41) Hence, The• fyy(x,y)=2 • fxy(x,y)=1 Then d =(2)(2)1=3 Since d =3> 0andfxx = 2 < 0, then we have a local maximum Example 5712 Find and classify all critical values for the following function f(x,y)=x3 12xy 8y3 First, we need to find the zeros of the partial derivatives Those partials are • fx(x,y)=3x2 12y • fy(x,y)=12x24y2 Set both of these

Transcript Ex63, 13 Solve the following system of inequalities graphically 4x 3y ≤ 60, y ≥ 2x, x ≥ 3, x, y ≥ 0 Now we solve 4x 3y ≤ 60 Lets first draw graph of 4x 3y = 60 Drawing graph Checking for (0,0) Putting x = 0, y = 0 4x 3y ≤ 60 4(0) 3(0) ≤ 60 0 ≤ 60 which is true Hence origin lies in plane 3x 4y ≤ 60 So, we shade left side of line Now we solve y ≥ 2x Economics questions and answers Suppose E X = 3 and E Y = 1 Evaluate the followings E 2X 1 E X Y E X 2Y Suppose V ar X = 1, V ar Y = 2, Cov X, Y = 0 Evaluate the following V ar X 2Y V ar X Y Cov 2X Y, X Suppose sigma_i = 1^n X_i = 3 and sigma_i = 1^infinity Y_i = 2 Evaluate the followings sigma_i = 1Theorem 3 says that any linear combination of solutions of (H) is also a solution of (H) Note that the equation y(x)=C1y1(x)C2y2(x) (1) where C1 and C2 are arbitrary constants, has the form of a general solution of equation (H) So the question is If y1 and y2 are solutions of (H), is the expression (1) the general solution of (H)?
Resuelve para "x" y para "y" "2x" menos "y" igual a 14 y por otra parte tengo "6x" más "3y" igual a 42 Y bueno, quiero resolver este sistema por el método de suma y resta o por el método de eliminación y para eso lo que quiero hacer es eliminar a la "y"Math Input NEW Use textbook math notation to enter your math Try it We have the quadratic equation #color(red)(y=f(x)=2x^2x3# Create a data table of values as shown below In the following table, you can see Column 1 (with x values) and Column 4 (with the corresponding y values) are shown Plot all the values from the table, to create the graph Obviously, from the table, for the value of #color(red)(y=0)#,

The function is y = x2 14x 9 x2 2x 3 ⇒, y(x2 2x 3) = (x2 14x 9) ⇒, yx2 2yx 3y = x2 14x 9 ⇒, yx2 −x2 2yx − 14x 3y − 9 = 0 ⇒, (y − 1)x2 (2y −14)x (3y − 9) = 0 This is a quadratic equation in x and in order to have solutions, the discriminant ≥ 0 Δ = b2 − 4ac ≥ 0 (2y − 14)2 − 4(y −1The yintercept is negative 2 So we go that's negative 1, negative 2 right there, and its slope is 3 And notice its slope is the same as the other line So it's going to have the same inclination If we move 1 in the xdirection, we move up 3 in the ydirection 1, up 3 Just like that If we go back 1 in x, we go down 3 Back 1 in x, we go
