Question

Which is not a solution of the inequality 10 - 4x greater then or equal to -6? A)0 b)2 c)4 d)5

Answer 1

A) can be a solution, but B), C), and D) cannot

Explanation:

Writing the inequality as math, we get
`10-4x\geq 6`. Substituting each value in and checking if it is correct gives us this:

A)
`10-4(0)\geq 6` gives us
`6\geq 6` which is TRUE

B)
`10-4(2)=2` which means that this is FALSE

Anything larger will also be false.
