the first one just means subtract use parentheses $5x+4-(2x+5)$

3. anonymous

you get a polynomial, in fact you get a line the domain of any polynomial is all real numbers

4. anonymous

the second one just means divide $\frac{5x+4}{2x+5}$

5. anonymous

to find the domain, set $$2x+5=0$$ and solve for $$x$$ then say "all real numbers except your answer"

6. anonymous

IS THE FIRST ONE 3X-1?

7. anonymous

1/3

8. anonymous

and the second one is -4/5

9. anonymous

yes, the first one is $$3x-1$$

10. anonymous

and domain is x not equal to -5/2

11. anonymous

that is for the domain of $$\frac{f(x)}{g(x)}$$ yes domain for $$a$$ is all real numbers

12. anonymous

yes

13. anonymous

i am not sure what you mean by "second one is -4/5"

14. anonymous

for b when i divide i get that answer

15. anonymous

looks like $$b$$ has two parts

16. anonymous

first answer is $$\frac{5x+4}{2x+5}$$

17. anonymous

that is the entire answer you cannot simplify this in any way

18. anonymous

so for both answers i leave them as functions? not fractions
