Answer:

y = 2x + \frac{x^2}{2} - 6

Step-by-step explanation:

Solution:-

- We are given the following initial value problem:

                             \frac{dy}{dx} = 2 + x , y ( 2 ) = -6

- We will first isolate the variables:

                            dy = ( 2 + x ).dx

- Perform integration for both sides of the equation:

                          \int {dy} = \int {( 2 + x )}.dx + c\\\\y = 2x + \frac{x^2}{2}  + c\\

Where,

                         c: The constant of integration

- We will solve for the constant of integration by using the initial value y ( 0 ) = -6 as follows:

                         -6 = 2(0) + \frac{0^2}{2} + c\\\\c = -6

- The final solution can be expressed  as follows:

                         y = 2x + \frac{x^2}{2} - 6

AB = x - 10, BC = x + 2, and AC = 28. Find BC.<br><br>Please help!
Leno4ka [110]

Answer:

BC = 20

Step-by-step explanation:

AC = AB + BC

28 = x-10 + x+2

Combine like terms

28 = 2x -8

Add 8 to each side

28+8 = 2x-8+8

36 = 2x

Divide by 2

36/2 = 2x/2

18 =x

We want to find BC

BC = x+2

     =18+2

     =20
