Homework Help: Algebra-Please check

Posted by Juliette on Tuesday, October 12, 2010 at 12:18pm.

5 - sqrt of 20x + 4 >= -3
5- 20x + 4 >= -3
5-4 - 20x >= -3
1 - 20x >= -3-1
-20x >= -4
x<= -15

Possible answers are
x<=3
-1/5 <= x<= 3
x >= -1/5
x >= 0

I think it is -1/5<=x<=3
because both solutions work
