SOMEONE HELP!! Lucy's goal for her cycling class at the gym is to burn 450 calories in one hour. The number of calories, c, she actually burns in one hour varies from her goal by no more than 45 calories. Which inequality represents this scenario? |c − 450| ≤ 45 |c + 450| ≥ 45 |c − 45| ≤ 450 |c + 45| ≥ 450

hm.........do you know this?

leila1234567:

like what does your brain think it is?

leila1234567:

he or she is not up here

JNJACK02:

I do this kind of math

JNJACK02:

idk

leila1234567:

oh ok

JNJACK02:

That would mean that you want x≤475 and x≥425 calories! The only inequality that fits this is A). Since |c - 450| ≤ 45 can be written as: -45≤c-450≤45 Add 450 to both sides and get 425≤c≤475, which is the same as x≤475 and x≥425 calories =)

I see

JNJACK02:

ok
