Solve 2 < 2x + 1 < 5; Solve for y: 3x + 5y = 8. 0-02. On Sabbath, Franklin's ... Graph y=23x−2. Graph y = –3x. Graph 3x – 4y = –12. 0-06. Describe the ... Bestimmen Sie das Volumen des RotationskSrpers, der durch Rotation des durch den Funktionsgraphen von y = x/x 2-16 (x e [ 4; 8 ]) und der. Jan 14, 2024 ... Solution For Find the separate equations of the lines represented by the equation x^2 - 4y^2 - 2x + 4y + 0.Ans: x -2y -2 = 0, x -2y = 0. over the compact region. −1 ≤ x ≤ 1, 0 ≤ y ≤ 2. Solution: We look for the critical points in the interior: ∇f = (2x − 2+2y,4y − 2+ ... (3x - 1)y00 - (3x + 2)y0 - (6x - 8)y = 0. By using the reduction of order formula, a second solution y2(x) is. (a) 3xe−x. (correct). (b) xex. (c) xe2x. (d) x2e− ... ... (-2) (x + 1) + 4/y-2). 2x-4y+z d) f(a)=√4-+2+2 = X. =-5. 2. S. X. DF (3) (x - 2 ) = ( ½, ÷ ) ( ~. १. The tangent plane is f. √ = x + √ √ 2 4 + 2 = 2√2. DF (a) = (. 13.8 Extrema of Functions of Two Variables. ET 12.8. 8. fx (x, y) = &x (x² + 3y² - 6xy ... Substituting this into the second equation gives-x+2(2x-6)=0⇒x= 4. 2 G(t, x)=3+² +46 +2 ох. 2. ว. 3+²+4t+2. J. ядай ox (x-1). 2. (x-1)2. Page 2 ... So it becomes μ(3x+2y=2x-y) = μ'(x) (x² + xy). 24. =>. C. = (x+4) if x to & μч0. ... (x, y) = x2 + y2 − 2x − 4y is ~i +j. Solution: The direction of fastest change is in the direction of ∇f =< 2x−2, 2y−4 > . Therefore we want ∇f =< 2x−2, 2y −4 > ...
