The function f(c)=9/5c+32 allows you to convert degrees celsius to degrees fahrenheit. find the inverse of the function so that you can convert degrees fahrenheit back to degrees celsius.

The function , convert degrees Fahrenheit back to degrees Celsius.

Step-by-step explanation:

Given : the function   allows to convert degrees Celsius to degrees Fahrenheit.

We have to find the inverse of the function so that you can convert degrees Fahrenheit back to degrees Celsius.

Since   convert degrees Celsius to degrees Fahrenheit.

So,   can be written as  , where F is temperature in degrees Fahrenheit. and  C is temperature in degrees Celsius.

Thus, to find the function that convert degrees Fahrenheit back to degrees Celsius.

Find the value of C in terms of F by solving ,

Subtract 32 both side, we have,

,

Multiply by we have,

,

Thus, the function , convert degrees Fahrenheit back to degrees Celsius.

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
