Question

Choose the correct description of the solution to the inequality x - 16 > 5x.


A.) Closed circle on -4, shading to the right.
B.) Open circle on -4, shading to the right.
C.) Closed circle on -4, shading to the left.
D.) Open circle on -4, shading to the left.

Answer 1

that's an "\(>\)" and not a "\(\ge\)" sign. So, has to be a hollow circle, isn't it? So open or close?

An solve that inequality to find which part would be shaded.

Answer 2

Its open. (:

Answer 3

Yup. :) And what about the shading? Can you solve this inequality and reduce it to it's simplest form?

Answer 4

Open circle on -4, shading to the left.

Combine like terms on the x, then put it on a graph. :)

Answer 5

Thank you guys!! (:

Answer 6

this is so because the inequality reduces to \(x<-4\)
