Answer:
- (d) (x² + y² + z²)³ = 27x²y²z²
Step-by-step explanation:
<u>Use the identity:</u>
- a³ + b³ + c³ = 3abc if a + b + c = 0
<u>Substitute as follows:</u>
<u>The sum of the cubes is:</u>
- x² + y² + z² = 3(xyz)
<u>Cube both sides:</u>
- (x² + y² + z²)³ = 27x²y²z²
Correct choice is (d)

Answer:
The graph with the vertical line.
Step-by-step explanation:
All vertical lines have an undefined slope. Horizontal lines have zero slope, and diagonal lines have a slope.
When calculating a slope for a vertical line, you would have to divide by zero. The quotient of any number and 0 are undefined, as you cannot divide by zero. This is what makes vertical lines have an undefined slope.
