It works out.

Hi, If a = -1, what is the solution set of the equation sqrt (x+ a) = x −7 {5} {10} {5, 10} No solution(5,10) correct? Thanks

Yes, that makes sense. And you're right: I'm not familiar with those equations.

It was rude and should not be condoned.

You are rude. Next time don't respond to any question I post.

There is no need to be rude. I just wanted to know if there was another way of doing it.

How do I solve this? Which of the following ordered pairs (x,y) satisfies the system of inequalities below? y>-3x+5 y≤ x-2 Choices: (2,1) (1,4) (4,1) (3,-6) Please. Thanks.

You can work a total of no more than 41 hours each week at your two jobs. Housecleaning pays \$6 per hour and your sales job pays \$9 per hour. You need to earn at least \$252 each week to pay your bills. Are the answers: x+y\le 41 6x+9y\ge252 How would you solve this? Thanks

Im not sure i understand how you derived those equations and what they mean.

I have \$15 to buy pencils and notebooks from a bookstore. If pencils are \$0.50 each and a notebook costs \$1.50, then how many pencils and notebooks can I buy if I spent all of the money? I reasoned: .5x+1.5x=15 x= 7.5 So 7 notebooks and 7 pencils. Is this correct?Thanks

Re: Solution to equations Thank you for your very detailed response.

Hi everyone, What is the solution set of the equation: sqrt{x+2}= x-4 I got 2 and 7. Is it correct or is it just 7. If so why? Thanks:)

Yes, the answers are reversed.

The guidelines state that the mean should be used if the values are similar, and that the median should be used if there are outliers, yet the answers are reversed.So I'm confused.

could someone please help?
