Answer:

Option D.

3 equations with 3 variables

Step-by-step explanation:

The coordinates of a point in space must necessarily have 3 components. One to describe the distance on the x axis, another to describe the distance on the y axis to the point, and a third to describe the distance on the z axis.

If we have three variables, then 3 equations are needed to solve the system. With less than 3 equations it would be impossible to solver the system.

Therefore the correct answer is option D.

3 equations with 3 variables

Solve -3x2 + 30x - 90 = 0.
FrozenT [24]
-3x^{2}+30x-90=0 \\  \\ x^{2}-10x+30=0 \\  \\ \Delta=(-10)^{2}-4*1*30=100-20=-20 \\  \\  \sqrt{\Delta}= \sqrt{-20}=i \sqrt{20}   =2i \sqrt{5}  \\  \\ x_{1}= \frac{10-2i \sqrt{5} }{2} = 5-i \sqrt{5}   \\  \\ x_{2}= \frac{10+2i \sqrt{5} }{2} = 5+i \sqrt{5}
