Answer: one and seven tenths
Step-by-step explanation:
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:
(-2, -2)
Step-by-step explanation:
The midpoint M is calculated from end points A and B as ...
M = (A +B)/2
Solving for end point B, we get ...
2M = A +B . . . . . . multiply by 2
B = 2M -A . . . . . . subtract A
Then the other end point is ...
B = 2(4, 3) -(10, 8) = (2·4 -10, 2·3 -8) = (8-10, 6-8)
B = (-2, -2)
The other end point has coordinates (-2, -2).
