Answer:

f(x) = 6x +1

Step-by-step explanation:

Differences in x-values (first row) are 1, 1, 1.

Differences in y-values (second row) are 6, 6, 6.

The constant ratio of differences (6/1) tells you the function is linear, and has a slope of m = 6/1 = 6.

Using the first point in the form ...

y = mx + b

we have ...

y = 6x + b

7 = 6·1 + b . . . . (x, y) = (1, 7)

1 = b . . . . . . subtract 6

Then the equation can be written ...

y = 6x +1

In functional form, this is ...

f(x) = 6x +1

I need to find the value of X

nirvana33 [79]

Answer:

17.7

Step-by-step explanation:

This figure is a pentagon - a shape with 5 sides. In a pentagon, the figure's angles add to 540.

100 + 7x-4 + 3x + 23 + 9x - 6 + 90 = 540

190 +19x + 13 = 540

203 + 19x = 540

19x = 337

x = 17.7

Use Newton’s Method to find the solution to the equation

Scorpion4ik [409]

$f(x) = - x {}^{2} + 18 \\ f'(x) = - 2x$

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

$x_{2} = 3 - \frac{f(3)}{f'(3)} = 4.5$

$x _{3}= 4.5 - \frac{f(4.5)}{f'(4.5)} = 4.25$

$x_{4} = 4.25 - \frac{f(4.25)}{f'(4.25)} ≈4.242647$

$x_{5} = 4.242647 - \frac{f(4.242647)}{f'(4.242647)} ≈4.242640 \\$
