Which expression represents 9 less than a number?
My name is Ann [436]

Answer:

x-9

Step-by-step explanation:

"Less than" switches the way of the expression.

If the "less than" was not there it would have been:

9-x

"Less" means subtract so you would subtract x from 9.

Hope this helped!

HELP, ASAP PLEASE!!!!
algol13

Answer:Remember that the general formula of geometric sequence is 

where 

is the nth term

is the difference

is the place of the term in the sequence

Also, to find  we will use the formula: 

where 

is the current term in the sequence 

is the previous term 

a) Lets find the three first terms of our sequence to check what type of sequence we have:

We know for our problem that the initial value of the computer is $1250, so our first term is 1250. In other words .

To fin our second term , we are going to subtract 10% of the value to our original value:

and , so 

To find our third term  we are going to subtract yet again 10% to our current value:

and , so

Now that we have our sequence  lets check if we have a consistent  to prove we have a geometric sequence:

- with , and :

 

- with , and :

 

Look! our s are the same, so we can conclude that we have a geometric sequence.

b) To do this we just need to replece the values of our sequence in the general formula of a geometric sequence. We know from our previous point that  and . So lets replace those values in geometric sequence formula to find our explicit formula:

c) To find the value of the computer at the beginning of the 6th year, we just need to find the 6th therm in our geometric sequence:

We can conclude that the value of the computer at the beginning of the 6th year will be $738.1125

Step-by-step explanation:

i did some research i dont know if it helped out not but id appreciate brainliest if it did..... thank you.

Find the inverse of the function f(x)=5x-6/x+2
Naily [24]

Answer:

  f^{-1}(x)=\dfrac{2x+6}{5-x}

Step-by-step explanation:

Swap x and y, then solve for y.

x=\dfrac{5y-6}{y+2}\\\\x(y+2)=5y-6\\\\xy+2x=5y-6\\\\2x+6=5y-xy\\\\y=\dfrac{2x+6}{5-x}\\\\f^{-1}(x)=\dfrac{2x+6}{5-x}
