Astudent claims than inequality 3x + 1 is greater than 0 is always true because multiplying a number by 3 and then adding 1/2 a result always produces a number greater than zero

This is not correct because if the x was any negative more than 1, it would always return an answer in the negatives:

x = -2

3(-2) + 1 = -5

x = -1

3(-1) + 1 = -2

So the student is wrong, because it is not always true, it is only greater than 0 when the x is bigger than a third.

1. minimum

2. 6400

3. eight

hope this !

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5

happy to
