**Algebra :]**

What is the doamin and range of: y= square root of (3-2x) The domain must be non-negative when we have a square root. Thus 3x-2 is greater than or equal to 0. The range will be non-negative too. All real y =>0. verify this.

**Math!!!!**

13.75 is the same as 12.5 plus a fraction of 12.5. What is the fraction? HELP. THANK YOU!! I would do this. 13.75 - 12.5 = 1.25 difference. 1.25 is 1-1/4 (one and one-fourth) and that is the same as 5/4. So 13.75 = 12.5 + 5/4. Check this out. 6=7\3=14
