Question

Is the inequality below sometimes, always, or never true?

-2(2x + 9) > -4x + 9
A. always
B. sometimes
C. never

Answer 1

distribute through the parenthesis first
-2(2x + 9) > -4x + 9
-4x - 18 > -4x + 9 --- add 18 to both sides
-4x > -4x + 9 + 18 -- add 4x to both sides
-4x + 4x > 9 + 18 -- combine terms
0 > 27
so is 0 greater then 27 ? Is it ever greater then 27 ?

that is your answer...it is NEVER greater then 27
