Web22 1 8 x −= 3 −. 60 Calculus AB ... ax() − a for the equation of the tangent line. The same answer could also be obtained with the correct tangent line ... not differentiable at x =1. However, it is continuous at this point. (B) This option is incorrect. The type of discontinuity was misidentified. Web(xw) = x dw dx + 1 x w = x(−x3) = −x4. Integration yields w(x) = − x4 5 + c1 x. The final solution is: y(x) = x+v(x) = x+1/w(x) or y(x) = x+ 5x c− x5. 4. Solve the following differential equations. (a) xy′ = p x2 +y2; (b) (1+x2)y′ + 2xy = 4x3. Solution (a) If we re–write the equation as y′ = p 1+ (y/x)2, we see that it is ...

WebApr 12, 2024 · Let us now discuss the formulas for the point of intersection of two lines in a plane. Assume the lines are given in the slope-intercept form equations, i.e.: \small y = a_1x+b_1\\ y = a_2x+b_2 y = a1x + b1 y = a2x + b2. Then the point of intersection, (x_0, y_0) (x0,y0), is given by the formula. \small x_0 = \frac { b_2-b_1} {a_1-a_2} \\ [0 ... WebFor solving the system of equations using the substitution method given two linear equations in x and y, express y in terms x in one of the equations and then substitute it in 2nd equation. Consider. 3x − y = 23 → (1) 4x + 3y = 48 → (2) From (1), we get: y = 3x − 23 → 3. Plug in y in (2), 4x + 3 (3x − 23) = 48. small screw light bulb holder
