Fudgin [204]2 years ago

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

Jane evaluates x squared minus 3 x + 5 for x = negative 2 below. Step 1: (negative 2) squared minus 3 (negative 2) + 5 Step 2: E
rjkz [21]

Answer:

Kindly check explanation

Step-by-step explanation:

Given the question :

Jane evaluates x squared minus 3 x + 5 for x = negative 2 below. Step 1: (negative 2) squared minus 3 (negative 2) + 5 Step 2: Equals negative 4 + 6 + 5 Step 3: Equals 7 What, if any, was Jane's mistake?

Jane's evaluation :

x² - 3x + 5 for x = - 2

Step 1:

(-2)² - 3(-2) + 5

Step 2:

-4 + 6 + 5

Step 3 :

= 7

Jane's mistake was in STEP2,

evaluating (-2)² = 4 and not - 4

Hence, (-2)² - 3(-2) + 5

= 4 + 6 + 5

= 15

Please help!!! I’m so confused on how to solve this!
-Dominant- [34]

Let's first write the equation given

x²+6x-13=0

They have told us to use "Completing the square" method.

So we need write x²+6x-13 as a whole square.

x²+6x-13=0

x²+(2*3*x)-9-4 = 0

x²+(2*3*x)-3²=4

Now we can write the LHS as:

(x - 3)²=2²

Hence,

x-3 can either be 2 or -2

Now,

x - 3=2

x=5

Or,

x - 3=-2

x=1

Therefore now we know that x can either be 1 or  5. So the correct answer is  Option B.
