Re: Algebra word problems

I have to go back to school tomorrow. I go full time three days a week and it seems like a long time. I wish the clock would stop and let me catch up.

Re: Algebra word problems

Hi;

Try that one and do not try anything else. Come back and tell me what happened.

Re: Algebra word problems

A message popped up:
To solve the inequality, you need to get y alone on the left side by using the addition and multiplication properties of inequality.
Strange problem.

Re: Algebra word problems

Try this, sometimes they want the -infinity to be an open interval.

Oh, wait they probably do not want interval notation.

Re: Algebra word problems

It says: The solution set in interval notation is_____ _____. So they want it in interval notation.
So if I change the bracket, it will work ya think?

Re: Algebra word problems

It took nicely. Thank you!
Solve the inequality, giving its solution set in both interval and graph forms. (i can do the graph.)
-7 (z - 6)> 3z - 8
(Simplify your answers. Type an integer or a decimal when needed)

Thank you so much.

5k-4/-9 >4
The solution set in interval form is (___, ___)

I noticed earlier the instructor gave the class Geometry homework, for the last week of classes. Now, that  will be hit or miss. I have never taken it before. I'm also working on that finance project in there. My calculator has been busy all night. LOL

Re: Algebra word problems

Hello, here is the message that popped up with that one:

"Neither end of the intervals is correct. Eliminate fractions by multiplying both sides of the inequality by a common denominator. Use the multiplication property inequality in the form k> constant or k< constant."
