What is the answer to this equation? 2(9+x) = -5(4-x)

photoshop1234 [79]

Answer:

Hi!

Alrighty here we go:

2(9+x)=-5(4-x)

18+2x=-20+5x

Now combine like terms

+20+18+2x=-20+20+5x

38+2x=5x

38+2x-2x=5x-2x

38=3x

x= 38/3

Hope this helped!

Answer:

$x_2 \approx -1.769$

Step-by-step explanation:

Let $f(x)=x^3+x+7$

So $f'(x)=3x^2+1$

$x_{n+1}=x_n-\frac{f(x_n)}{f'(x_n)}$

Let $x_1=-2$

We are going to find $x_2$

So we are evaluating $-2-\frac{f(-2)}{f'(-2)}$

First step find f(-2)

Second step find f'(-2)

Third step plug in those values and apply PEMDAS!

$f(-2)=(-2)^3+(-2)+7=-8-2+7=-10+7=-3$

$f'(-2)=3(-2)^2+1=3(4)+1=12+1=13$

$x_2=-2-\frac{-3}{13} \\\\ x_2=\frac{-26+3}{13} \\\\ x_2=\frac{-23}{13} \\\\ x_2 \approx -1.769$
