J. The equation has one real solution and two complex solutions.

Step-by-step explanation:

Complex solutions come in pairs, so there can only be an even number of them.  So we can rule out G, H, and K.

To find the other roots, we can factor using either long division or grouping.  To use long division, see the attached picture.  To use grouping:

3x³ − 4x² + x − 10 = 0

3x³ − 6x² + 2x² + x − 10 = 0

3x² (x − 2) + (2x + 5) (x − 2) = 0

(x − 2) (3x² + 2x + 5) = 0

The other factor is 3x² + 2x + 5.  The discriminant of this is (2)² − 4(3)(5) = -56.  Since the discriminant is negative, the roots are complex.

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
