Can you subtract 7-m?

Mathematics
2 answers:
LenKa [72]3 years ago

Answer:

NO unless you know the value of m you are able to subtract a variable form a constant unless the constant is attached to the same variable. For example you can sub tract 7m-m and that would equal 6m but you can not subtract 7b-m because the variables are different. If you tink about it this way 7 can have the variable A attached to it to make it 7a and the variable m can be thought of as 1m. Therefor you can not have 7a-1m because the variables are different.

Answer:

if this is in an inequality problem no because you can only combine like terms such as combining m and m and no variable numbers together you cannot subtract a variable from a number unless you have what the variable is equal to. correct me if im wrong

Describe the end behavior of a 14th degree polynomial with a positive leading coefficient.
DiKsa [7]

<u><em>Answer:</em></u>

1)

f(x)→ ∞ when x→∞ or x→ -∞.

2)

when  x→ ∞ then f(x)→ -∞

        and when x→ -∞ then f(x)→ ∞

<u><em>Step-by-step explanation:</em></u>

<em>" The </em><em>end behavior</em><em> of a polynomial function is the behavior of the graph of as approaches positive infinity or negative infinity. The degree and the leading coefficient of a polynomial function determine the end behavior of the graph "</em>

1)

a 14th degree polynomial with a positive leading coefficient.

Let f(x) be the polynomial function.

Since the degree is an even number and also the leading coefficient is positive so when we put negative or positive infinity to the function i.e. we put x→∞ or x→ -∞ ; it will always lead the function to positive infinity

i.e. f(x)→ ∞ when x→∞ or x→ -∞.

2)

a 9th degree polynomial with a negative leading coefficient.

As the degree of the polynomial is odd and also the leading coefficient is negative.

Hence when x→ ∞ then f(x)→ -∞ since the odd power of x will take it to positive infinity but the negative sign of the leading coefficient will take it to negative infinity.

When x→ -∞ then f(x)→ ∞; since the odd power of x will take it to negative infinity but the negative sign of the leading coefficient will take it to positive infinity.

Hence, when  x→ ∞ then f(x)→ -∞

        and when x→ -∞ then f(x)→ ∞

Which expression is equivalent to g^−m ÷ g^n
WINSTONCH [101]
G^−m ÷ g^n

1st g^−m=1/g^m, hence g^−m ÷ g^n = (1/g^m) /(g^n)==> 1/(g^m)(g^(n)
==> 1/(g^m+n) or g^(-m-n)
