Question

Find the solution set of this inequality. Enter your answer in interval notation using grouping symbols.
|-2x+1|<=5

Answer 1

-2x+1<5
-2x<4
x>2 (2,int)
2x-1<5
2x<6
(3,inf)

Answer 2

i dont get it

Answer 3

wait NO
[2,inf) and (-inf,3]

Answer 4

|x|=+x and also -x so you have to solve two systems

Answer 5

i cant put letters tho

Answer 6

\[|-2x+1|\le5\]
First, we remove the absolute value sign by rewriting the equation as follows:
\[-2x+1 \le \pm5\]
Now we can solve.
First solution:
\[-2x \le 4\]
x > -2
Second solution:
\[-2x \le -5\]
x > 5/2
