It doesn't matter if there is 0, you still flip the inequality symbol.
-3z <span>≥ 0
z </span>≤ 0
Answer:
15x + 9 (We combing like terms. Ex. 16x and -x)
The system of equations does not have a solution.
For example, imagine these two equations y = x + 7 and y = x + 9
Now subsitute y in the second equation with the value from the first equation:
x + 7 = x + 9
x - x + 7 = 9
0 + 7 = 9
7 = 9.
That happens because the equations represent parallel lines, which do not have a common pair of points.

Answer:
Volume = 33.51 m^3
Step-by-step explanation:
<u>Formula for a Sphere: V = 4
/3 * π * r^3</u>
<u />
<u>Step 1: Plug in</u>
V = 4
/3 * π * (2)^3
V = 4/3 * π * 8
V = c
<em>V = 33.51</em>
