5 0

Answer:

The answer is approximately 2.21456

Step-by-step explanation:

1. You simplify your equation to:

5x^3-11x-30=0

2. Now you can use the Newton Raphson method to solve this problem.

The Newton Raphson method can be used by calculating x + 1 until its delta turns into something below 0.00001, and the x value is your answer.

-9b-6=-3b +48<br> Step by step
Travka [436]

Answer:

b = -9

Step-by-step explanation:

1. Move the variables to the left side. Be sure to change the terms (add/subtract)

-9b-6 = -3b+48

-9b+3b-6 = 48

2. Combine like terms.

-9b+3b-6 = 48

-6b = 48 + 6

3. Divide both sides by -6.

-6b = 54

b = -9
