Question

Solve for x.

15 ≥ -3x or 2/5 x ≥ -2

{x | x ≤ -5}
{x | x ≥ -5}
{all reals}

Answer 1

so first lets solve 15>= - 3x

divide both sides by -3 and redo the sign >= into =<

-5=<x

now about the second

2/5x >= -2

multiply eah side by 5/2
x>=-2*5/2
x>=-5

Answer 2

both equations gave the same answer, so the final answer will be x bigger or equal to -5.

Answer 3

so B?
