Answer:

Step-by-step explanation:

Since we do not know the value of n, we can't write an equation for this. You could also write it as 5n + 6.7 if you'd like. Since letters and numbers don't mix, we can't add 6.7 to 5n. I rounded 6.7 to 7 in my answer. Hope this helped.

Solve the system x+y=0 −2x−y=8 *Answer should be in ( x , y ) form, will give 40 points *

Answers

Answer:

x = -8 and y= 8

(-8,8) is the answer

Answer:

(2,4) (-4,16)

Step-by-step explanation:

Subtract 2 x from both sides of the equation.

y = 8 − 2 x

Substitute 8 − 2 x for y into x ^2 − y = 0 then solve for x .

x = 2 , − 4

Substitute 2 for x into x 2 − y = 0 then solve for y .

y=4

Substitute − 4 for x into x 2 − y = 0 then solve for y .

y=16

Equation form

x = 2 , y = 4

x = − 4 , y = 16

Point B is the center of the circle shown, and the length of arc AC is 8π. What is the area of the circle?

Answers

Answer:

[tex]A=324\pi \text{ units}^2\approx1017.88\text{ units}^2[/tex]

Step-by-step explanation:

The formula for arc length is:

[tex]\stackrel{\frown}{A}=2\pi r(\frac{\theta}{360}})[/tex]

Where Θ is measured in degrees.

We know that the arc length is 8π when the degree is 80. So, substitute 8π for A and 80 for Θ:

[tex]8\pi=2\pi r(\frac{80}{360})[/tex]

Divide both sides by 2π:

[tex]4=r\frac{80}{360}[/tex]

Simplify the fraction:

[tex]4=\frac{2}{9}r[/tex]

Multiply both sides by 9/2:

[tex]r=18[/tex]

So, the radius is 18.

Now, we can find the area of the circle. The formula for the area of a circle is:

[tex]A=\pi r^2[/tex]

Substitute 18 into r:

[tex]A=\pi (18)^2[/tex]

Simplify:

[tex]A=324\pi \text{ units}^2\approx1017.88\text{ units}^2[/tex]

And we're done!
