Water = 5 bottles * $0.90 = $4.50
meat = 8 pounds * x amount.
Total = water + meat prices = $26.90
26.90 = $4.50 + 8x
22.40 = 8x
2.8 = x
The price per pound of meat is $2.80.
F(x) = 3x² + 6x - 1
The graph is a parabola open upward (a= 3>0) with a minimum.
Calculate the vertex:
x = -b/2a → x = -6/(2.3) = -1. Then the axis of symmetry is x = - 1
Now to calculate the minimum, plugin the value of x:
y = 3x² + 6x - 1
y = 3(-1)² + 6(-1) -1
y= 3 - 6 -1 and y = - 4,
Ten the vertex (minimum) is at (-1,- 4)

Answer:


Step-by-step explanation:
4x - 3y = 1
x + 3y = 0
Req To Solve With Elimination:
Make Them Equal:
-> 4x - 3y = 1
-> 4x + 4 . 3y = 0
Simplify:
-> 4x - 3y = 1
-> 4x + 12y = 0
-> 4x - 4x - 3y - 12y = 1
-> -3y - 12y = 1
-> -15y = 1
-> 
->

Answer:
3053.63 un³
Step-by-step explanation:
Hello!
The diameter is 18, so the radius is half of the diameter, or 9.
Using the volume of a sphere formula: 
Solve:




- 3,053.6280592893 ≈ 3,053.63
The volume is 3053.63 un³.
