Question

Solve the inequality Write the solution in set builder notation 
-2x-13≥-25 ?
HELP PLEASE !

anonymous · Answer

what is a set builder notation?
anyways i can help you solve the inequality
it works mostly like if you were to solve an equation
so
-2x-13 (>or=) -25                    sorry i cant type symbols
add 13 to both sides

anonymous · Answer

then you get -2x (> or =) -12

anonymous · Answer

now to get x on its own you divide by -2 from both sides

kamille · Answer

$$-2x \ge-25+13$$ add 25+13 and then divide by (-2). Don't forget to change sign into another (from $$from \ge \to l$$

kamille · Answer

$$from \ge $$ 
to <(or=)

anonymous · Answer

I just need the answer because I don't really get nothing of this.

anonymous · Answer

now you are not done yet 
whenever you have to divide or multiply by a negetive number you have to change the sign
so the answer is NOT: x (> or =) 6
but it is: x (< or =) 6
