Answer:
-7
Step-by-step explanation:
y-3=-2(x+5)
So we need to put this in slope-intercept form...
y - 3 = -2x -10 (You use the distributive property)
Then shift the -3 over to meet the other constant -10 by addition.
y - 3 = -2x -10
+3 + 3
y = -2x -7 since y = mx + b is in slope intercept form m = slope and b = y intercept, therefore the y intercept is -7

Answer:
diameter=22
circumference=22pi
Step-by-step explanation:
diameter=2*radius
so 2*11=22
circumference=2pi*r
=2*11*pi
=22pi

I think you asked for a ratio?
Answer: ![\pi =\frac{47.1}{15}](https://tex.z-dn.net/?f=%5Cpi%20%3D%5Cfrac%7B47.1%7D%7B15%7D)
Step-by-step explanation:
The complete exercise is: "The circumference of a circle is 47.1 and the diameter of the circle is 15. Which best represents the value of π? "
In order to solve this exercise, it is important to remember that the circle can be calculated with the following formulas:
1. ![C=\pi D](https://tex.z-dn.net/?f=C%3D%5Cpi%20D)
Where "C" is the circumference of the circle and "D" is the diameter of the circle.
2. ![C=2\pi r](https://tex.z-dn.net/?f=C%3D2%5Cpi%20r)
Where "C" is the circumference of the circle and "r" is the radius of the circle (Remeber that the diameter is twice the radius).
In this case, the exercise gives you the circumference of the circle and its diameter. These are:
![C=47.1\\\\d=15](https://tex.z-dn.net/?f=C%3D47.1%5C%5C%5C%5Cd%3D15)
Then, knowing those values, you can substitute them s into the first equation
, as following:
![47.1=\pi (15)](https://tex.z-dn.net/?f=47.1%3D%5Cpi%20%2815%29)
The final step is to solve for
:
![\pi =\frac{47.1}{15}](https://tex.z-dn.net/?f=%5Cpi%20%3D%5Cfrac%7B47.1%7D%7B15%7D)
the correct answer should be 2radical 13
