1. eli123 Group Title

2. satellite73 Group Title

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

3. satellite73 Group Title

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

4. satellite73 Group Title

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

5. satellite73 Group Title

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

6. eli123 Group Title

IS THE FIRST ONE 3X-1?

7. eli123 Group Title

1/3

8. eli123 Group Title

and the second one is -4/5

9. satellite73 Group Title

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

10. eli123 Group Title

and domain is x not equal to -5/2

11. satellite73 Group Title

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

12. eli123 Group Title

yes

13. satellite73 Group Title

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

14. eli123 Group Title

for b when i divide i get that answer

15. satellite73 Group Title

looks like $$b$$ has two parts

16. satellite73 Group Title

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

17. satellite73 Group Title

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

18. eli123 Group Title

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