Answer:

P = 10x³ + 4x² + 8x + 6

Step-by-step explanation:

The perimeter of a rectangle is twice the sum of length and width.

P = 2(L+W) = 2((x³ +2x² -6x +12) +(4x³ +10x -9))

= 2(5x³ +2x² +4x +3) . . . . collect terms inside parentheses

P = 10x³ +4x² +8x +6

What is the equation of a line, in point- slope form, that passes through (5, -3) and has a slope of 2/3?

Alika [10]

<h3><u><em>Option B</em></u></h3><h3><u><em>The equation of a line, in point- slope form, that passes through (5, -3) and has a slope of 2/3</em></u></h3><h3><u><em /></u> $y + 3 = \frac{2}{3}(x -5)$ <u><em /></u></h3>

<em><u>Solution:</u></em>

<em><u>The equation of line in point slope form is given as:</u></em>

$y - y_1 = m(x-x_1)$

Where, "m" is the slope of line

Given that,

slope = 2/3

$m = \frac{2}{3}$

The line passes through (5, -3)

Substitute m = 2/3 and $(x_1, y_1)$ = (5, -3) in point slope form

$y - (-3) = \frac{2}{3}(x -5)\\\\y + 3 = \frac{2}{3}(x -5)$

Thus equation of line in point slope form is found

Write an equation of the line below.

Hello!

The equation would be y= -2/6x + (-3). Since, the y-intercept is -3 and the slope/growth is -2/6 (it's decreasing).

To find the slope just make a growth triangle. We go down twice (then to the right 6 times).
