In the 
plane, we have 
everywhere. So in the equation of the sphere, we have
which is a circle centered at (2, -10, 0) of radius 4.
In the 
plane, we have 
, which gives
But any squared real quantity is positive, so there is no intersection between the sphere and this plane.
In the 
plane, 
, so
which is a circle centered at (0, -10, 3) of radius 
.

Answer:
14.4 or 15 bags
Step-by-step explanation:
The number of yards covered by x bags is ...
(3 1/2)x = 50 1/4
x = (50 1/4)/(3 1/2) = 50.25/3.5 ≈ 14.4*
We assume that bags of chips are available only in integer quantities.
The PTA will need 15 bags of wood chips to cover the wet section.
_____
* The exact answer is 14 5/14. We hope that an integer number is the desired solution, as anything more precise than that seems inappropriate in this context.
Answer:
True
Step-by-step explanation:
3k-14=3(k-5)+1
3k-14=3k-15+1
3k-3k=14-15+1
0=14-15+1
-14=-15+1
-14=-14
Answer:
y = 5-3x
Step-by-step explanation:
First, you want to divide both sides of the equation by 3, so we have the equation in the simplest form. Thus, we have an equation: 3x + y = 5.
Slope intercept form means the equation is in the y = mx + b form. In this case, y is y, m is 3 (coefficient of x) x is x, and b is 5. So, subtracting 3x from both sides means we have our answer of y=5-3x.
