Answer:

Step-by-step explanation:

Point slope form is y-y1=m(x-x1)

(x1,y1) is (-9,-3)

m is -6

Plug in!

y-(-3)=(-6)(x-(-9)) The answer could look like this.

y+3=-6(x+9) Or this.

y=-6(x+9)-3 Or this

y=-6x-54-3 Even this but unlikely...

y=-6x-57 Or this.

I will change my answer after choices are posted.

Answer:

y+3 = -6(x+9) point slope form

y = -6x-57 slope intercept form

Step-by-step explanation:

We can use the point slope equation of a line

y-y1 = m(x-x1)

y--3 = -6(x--9)

y+3 = -6(x+9)

If we want the equation in point slope form

Distribute the -6

y+3 = -6x -54

Subtract 3 from each side

y+3-3 = -5x-54 -3

y = -6x-57

Describe two reasons for using a variable. Write your response using 4-5 complete sentences.

SVEN [57.7K]

One reason would be if you did not know the answer so you could do
4-5=x
another reason would be if the problem gave you the answer but not one of the things to get the answer
4-x=-1
not sure if that is what you want but I hope this helped

Find the area of the regular polygon. Round to the nearest tenth.

mojhsa [17]

Given:

Side length = 12 in

To find:

The area of the regular polygon.

Solution:

Number of sides (n) = 6

Let us find the apothem using formula:

$$a=\frac{s}{2 \tan \left(\frac{180^\circ}{n}\right)}$

where s is side length and n is number of sides.

$$a=\frac{12}{2 \tan \left(\frac{180^\circ}{6}\right)}$

$$a=\frac{6}{ \tan (30^\circ)}$

$$a=\frac{6}{ \frac{1}{\sqrt{3} }}$

$$a=6\sqrt{3}$

Area of the regular polygon:

$A=\frac{1}{2}(\text { Perimeter })(\text { apothem })$

$$A=\frac{1}{2}(6 \times 12)(6\sqrt{3} )$

$$A=\frac{1}{2}(72)(6\sqrt{3} )$

$A=216 \sqrt{3}$

$A=374.1$ in²

The area of the regular polygon is 374.1 in².
