Question

HELPPPP

Answer 1

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

Answer 2

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

Answer 3

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

Answer 4

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

Answer 5

IS THE FIRST ONE 3X-1?

Answer 6

1/3

Answer 7

and the second one is -4/5

Answer 8

yes, the first one is \(3x-1\)

Answer 9

and domain is x not equal to -5/2

Answer 10

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

Answer 11

yes

Answer 12

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

Answer 13

for b when i divide i get that answer

Answer 14

looks like \(b\) has two parts

Answer 15

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

Answer 16

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

Answer 17

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