F(x)=2x+3/4x+5
find f(-9)

Answers

Answer 1

Answer:

$\huge\textsf{Hey there!}$

$\mathsf{f(x) = (2x + 3)/(4x + 5)}$

$\mathsf{y = ( 2x + 3)/(4x + 5)}$

$\mathsf{y = (2(-9) + 3)/(4(-9) + 5)}$

$\mathsf{2(-9)}$

$\mathsf{\bf = -18}$

$\mathsf{y = \frac{-18 + 3} {4(-9) + 5}}$

$\mathsf{-18 + 3}\n\mathsf{= \bf -15}$

$\mathsf{y = \frac{ -15} {4(-9) + 5}}$

$\mathsf{4(-9)}\n\mathsf{\bf = -36}$

$\mathsf{y = (-15)/(-36 + 5)}$

$\mathsf{-36 + 5}\n\mathsf{= \bf-31}$

$\mathsf{y = (-15)/( -31)\rightarrow\boxed{\bf (15)/(31)}}$

$\boxed{\boxed{\huge\text{Answer: } \boxed{\bf f(-9) = (15)/(31)}}}\huge\checkmark$

Answer 2

Answer:

$\implies {\blue {\boxed {\boxed {\purple {\sf { f(-9)= 0.48}}}}}}$

$\large\mathfrak{{\pmb{\underline{\orange{Step-by-step\:explanation}}{\orange{:}}}}}$

$f(x) = (2x + 3)/(4x + 5) \n$

For $f(-9)$ , put " $-9$ " for every value of " $x$ ".

$↬f( - 9) = (2( - 9) + 3)/(4( - 9) + 5)\n$

$↬ f(-9) = ( - 18 + 3)/( - 36 + 5) \n$

$↬ f(-9) = ( - 15)/( - 31)\n$

$↬ f(-9)= (15)/(31)\n$

$↬f(-9)= 0.48\n$

A _____ is a rule that assigns each value of the independent variable to exactly one value of the dependent variable.

Answers

A function is a rule that assigns each vale of the independent variable to exactly one vale of the dependent variable.

The missing word is the function.

Point to remember:

The definition says that two values of x(independent variable ) may correspond to one value of y(dependent variable) but the vice versa is not true( means two values of y(dependent variable ) does not correspond to one value of x(independent variable) ). This explanation is very powerful tool to check that whether a relation is a function or not.

Answer:Function

A function is a rule that assigns each value of the independent variable to exactly one value of the dependent variable.

Factor the polynomial below.

Answers

Answer:

option-A

Step-by-step explanation:

we are given

$6b^2+3b$

we can factor each terms

and then we can take common terms among them

$6b^2=2* 3* b* b$

$3b=1* 3* b$

we can replace it

and we get

$6b^2+3b=2* 3* b* b +1* 3* b$

now, we can take out common terms

we can see that common terms are 3 and b

$6b^2+3b=3b(2* b+1)$

we can simplify it

$6b^2+3b=3b(2b+1)$

Answer:

Its A.

Step-by-step explanation:

6b^2 + 3b.

The GCF is 3b so we divide this into the expression giving the factors:-

3b(2b + 1) (answer).

(01.01 MC)Why is 3 + (−5) equal to −2? Because it is 5 units to the left of 0 on a horizontal number line Because it is 5 units to the right of 3 on a horizontal number line Because it is 5 units to the left of 3 on a horizontal number line Because it is 5 units to the right of 0 on a horizontal number line

Answers

Answer:

C. Because it is 5 units to the left of 3 on a horizontal number line

Step-by-step explanation:

Directed numbers are numbers which has direction i.e either a negative or positive sign before it. This implies that all numbers are directed, since a number without a sign is taken to be positive.

Thus from the given expression,

3 + (-5) = 3 - 5

= -2

So that,

3 + (-5) = -2

Expressing this on the number line, -2 is 5 units to the left of 3. Thus option C is appropriate.
