Answer:

y-8=-4/3(x+2)

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-4-8)/(7-(-2))

m=-12/(7+2)

m=-12/9

simplify

m=-4/3

y-y1=m(x-x1)

y-8=-4/3(x-(-2))

y-8=-4/3(x+2)

Find the area of the circle.<br> 12 ft

Ratling [72]

Answer:

Area of the circle is 113.04 ft²

Step-by-step explanation:

Given:

Diameter of circle = 12 feet

To Find:

Area of the circle

Using formula:

$\\ \: \: \dashrightarrow \: \: \:{\underline{\boxed{ \bf{Area_{( circle)} = \pi r^2}}}} \\ \\$

<em>Where,</em>

π = 3.14
Diameter = 12 feet
Radius = 12/2 = 6 feet

On substituting the required values, we get:

$\\ \: \: \dashrightarrow \: \: \: \sf Area_{(Circle)} = 3.14 \times {(6)}^{2} \\ \\ \\ \: \: \dashrightarrow \: \: \: \sf Area_{(Circle)} = 3.14 \times 36 \\ \\ \\ \: \: \dashrightarrow \: \: \: \sf Area_{(Circle)} = 113.04 \: {ft}^{2} \\ \\ \\$

Hence,

Area of the circle is<u> </u>113.04 ft²

What is the mistake NEED ANSWER ASAP

julsineya [31]

Answer:

The answers are in the image.

Step-by-step explanation:

Charlie made the mistake by not getting the equation equal to zero.

$x^2 - 9x + 8 = 16$

Subtract 16 to both sides making it equal to 0.

$x^2 - 9x - 8 = 0$

The Slope of lines parallel to line is 1/2 and the Slope of lines perpendicular to line is -2.

<h3>What is the equation of a straight line ?</h3>

An equation that can be written in the form of y = mx+c

where m is the slope of the line

and c is the intercept on y axis

The equation given in the question is

y=1/2x−7

in this the slope = 1/2

Intercept = -7

For parallel Lines

For a parallel line , the slope of the line is same

and is given by m = 1/2

For a perpendicular line

Slope will be equal to

-1/m

here -1/m = -2

Therefore the slope for perpendicular line is -2.

Let's factor x^2−22x+121

The middle number is -22 and the last number is 121. Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks? We need two numbers that...

Add together to get -22

Multiply together to get 121

Can you think of the two numbers?

Try -11 and -11:

-11+-11 = -22

-11*-11 = 121

Fill in the blanks in

(x+_)(x+_)

with -11 and -11 to get...

(x-11)(x-11)

Answer: (x-11)(x-11)

Hope this helps!!!
