Dividing by 2 is the same as multiplying by 1/2.
2462 * 1/2 = 1231
Answer:
D
Step-by-step explanation:
Just go with it I took the class
In point slope form, the equation is y-7=(-10/3)(x+9). In slope-intercept form, it is y=(-10/3)x-23.
First find the slope of the line. The formula for slope is
m=(y₂-y₁)/(x₂-x₁)
Using our points, we have
m=(-3-7)/(-6--9) = -10/3
Plug this into point slope form:
y-y₁=m(x-x₁)
y-7=(-10/3)(x--9)
y-7=(-10/3)(x+9)
Using the distributive property:
y-7=(-10/3)*x+(-10/3)*9
y-7=(-10/3)x-90/3
y-7=(-10/3)x-30
Add 7 to both sides:
y=(-10/3)x-23

Answer:
--- small circle
--- big circle
Step-by-step explanation:
Given
-- sum of areas
Required
The radius of the larger circle
Area is calculated as;
For the smaller circle, we have:
For the big, we have
The sum of both is:

![80\pi = \pi[ r^2 + 4r^2]](https://tex.z-dn.net/?f=80%5Cpi%20%3D%20%5Cpi%5B%20r%5E2%20%2B%204r%5E2%5D)
![80\pi = \pi[ 5r^2]](https://tex.z-dn.net/?f=80%5Cpi%20%3D%20%5Cpi%5B%205r%5E2%5D)
Divide both sides by 
Divide both sides by 5
Take square roots of both sides
The radius of the larger circle is:
