Question 5 • Algebra II

What is the solution of the fraction with numerator x plus 8 and denominator 5 x minus 1 is greater than 0 ?

Answer
A
negative 8 is less than x comma x is less than 1 fifth
B
x is less than negative 8 or x is greater than 1 fifth
C
x is less than or equal to negative 8 or x is greater than 1 fifth
D
negative 8 is less than or equal to x comma x is less than 1 fifth

Explanation

The fraction can change sign at x = -8, where the numerator is zero, and x = 1/5, where the denominator is zero. Testing the intervals shows the fraction is positive when x < -8 or x > 1/5. Both endpoints are excluded because the inequality is strict, and the denominator cannot be zero. Therefore, the solution is “x is less than negative 8 or x is greater than 1 fifth.”
