Question

What is the solution to the inequality x2 < 16 – 6x?

Question 7 options:

A)

x < –8 or x > 2

B)

x < –8 and x > 2

C)

–8 ≤ x ≤ 2

D)

–8 < x < 2

Answer 1

D

Explanation:

2x < 16 - 6x

Bring the variables to one side

2x < 16 - 6x

+6x +6x

8x < 16

Divide both sides by the coefficient

8x/8 < 16?8

x < 2
