I'm having a difficult time figuring out some of these! For some reason the -1 in this problem is throwing me off - I think! Here's what I came up with last time, I keep getting a different answer each time I work it.
3/(y+5) -1 = (4-y)/(2y+10)
3/(y+5)-1 = (4-y)/2(y+5)
y is not equal to -5
LCD is 2(y+5)
2(y+5)*3/(y+5) =
Please help with the following rationalexpressions and to simplify.
Find each function value
2) f(y) = y - 2 / -5 + y; f(-5), f(0), f(10)
6) g(x) 4 -3x / 2
10) f(x) = -4x/-2 + x
14) h(x) = 5 -3x / 2x^2 - 14x + 20

The description below tells of the properties of rational numbers is very good and comprehensive. However, please describe how it relates to RATIONALEXPRESSIONS?
A rational number is a number that can be expressed as a fraction, ratio of two integers or decimal number. Rational numbers can be ordered in a number line.

(1) Explain how multiplying and dividing rationalexpressions is similar to multiplication and division of fractions. Give an example of each and compare the process.
(2) When simplifying the rational expression (x+8)/(x+2), explain why it is improper to cancel out the x's. State a general rule for canceling factors in a rati
