Multiply by 6 and simplify
.. x = 6*12/9 = 72/9 = 8
x = 8
Answer:
Step-by-step explanation:
The solution is the coordinates of the point where the lines intersect: (3,5)
Answer:
The volume of the hemisphere is 496741.6 m³
Step-by-step explanation:
The volume of an sphere is given by:

In which
and r is the radius.
An hemisphere is half of an sphere, so it's volume is half the sphere's volume. So

In this question:
. So

The volume of the hemisphere is 496741.6 m³
Answer:
39
Step-by-step explanation:
you need to work backwards
86-2-6=78
therefore, 78 = 2y
y = 2y/2, so 78/2 = 39
Answer: 
<u>Step-by-step explanation:</u>
(1, 2) and (4, -3)
First, find the slope (m): 
m = 
= 
Next, choose ONE of the points and input the point and slope into the Point-Slope formula: y - y₁ = m(x - x₁)
y - 2 =
(x - 1)
y - 2 =
+ 
y =
+ 
Then, determine which inequality symbol will result in (-2, 8) being False (since it is not a solution):
y ___
+ 
8 ___
+ 
8 ___ 
8 >
so ≤ makes the statement False
⇒ y ≤
+ 
****************************************************************
If you need a "system" of inequalities, then you need another equation.
There are infinite possibilities. Graph the points to see what works.
y < 8 or x > -2 are two examples.
---> I just realized that the system can be simpler than what I did above:
