What is the equation of the following line? Be sure to scroll down first to see all answer options. 10 (2, 10) (0, 0) - 10 10 2

sashaice [31]

to get the the equation of any straight line, we only need two points off of it, let's use the two points already in the picture.

$(\stackrel{x_1}{2}~,~\stackrel{y_1}{10})\qquad (\stackrel{x_2}{0}~,~\stackrel{y_2}{0}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{0}-\stackrel{y1}{10}}}{\underset{run} {\underset{x_2}{0}-\underset{x_1}{2}}}\implies \cfrac{-10}{-2}\implies 5 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{10}=\stackrel{m}{5}(x-\stackrel{x_1}{2}) \\\\\\ y-10=5x-10\implies y=5x$

The perimeter of a rectangle with sides x+6 and x-6 is equal to 48 inches. What is the value of x?

larisa86 [58]

(Since the perimeter is the length of each sides added up. Two sides are equal to x+6 and two are equal to x-6)

2 (x+6) + 2 (x-6) = 48

(break out the brackets)

2x + 12 + 2x -12 = 48

( 12 and -12 cancel out and "disappear".)

2x + 2x = 48

4x = 48

(Rearrange for x)

x = 48 / 4

x = 12 inches

Draw a right triangle with one leg value is 4 and the other leg value is 3. Use the triangle to find the exact values of the six

Nina [5.8K]

Step-by-step explanation:

Draw a right triangle with one leg value is 4 and the other leg value is 3

The triangle is attached below

To find hypotenuse , use Pythagorean theorem

$c^{2} =a^{2} +b^{2} \\c^{2} =3^{2} +4^{2} \\\\c^{2} =25 \\\\c=\sqrt{25} =5$

opposite side = 4, adjacent side =3 and hypotenuse = 5

Apply trigonometric ratios

$sin(A)=\frac{opposite}{hypotenuse}=\frac{4}{5}$

$cos(A)=\frac{adjacent}{hypotenuse}=\frac{3}{5}$

$tan(A)=\frac{opposite}{adjacent}=\frac{4}{3}$

$cosec(A)=\frac{hypotenuse}{opposite}=\frac{5}{4}$

$sec(A)=\frac{hypotenuse}{adjacent}=\frac{5}{3}$

$cot(A)=\frac{adjacent}{opposite}=\frac{3}{4}$

What is the slope of the line? <br><br> 1. -2<br><br> 2. -1/2<br><br> 3. 1/2<br><br> 4. 2

postnew [5]

Slope formula : slope = (y2 - y1) / (x2 - x1)
(2,3)...x1 = 2 and y1 = 3
(4,2)... x2 = 4 and y2 = 2

now we sub and solve
slope = (2 - 3) / (4 - 2) = -1/2 <==

MArishka [77]

Answer:

I am not 100 percent sure, it's been a long time since I've done this type of math but I think that these are the answers

Step-by-step explanation:

1. x= -3, y=-3

2. x= 5, y= -2

3. x= -3, y = -7

4. x=2, y= 1

5. x=0, y= -4
