3 x
---------= --------- ---------
15 180
15x=540
----- ------= 36 students.
15 15
Steps: Cross multiply to get 15x and 540. Divide both numbers by 15, then you found what x equals, which is the answer.
Answer:
1436.02
Step-by-step explanation:
Notice that we have common denominator 2, so we can split the denominator to express the function in the form

where

is the slope

is the y-intercept


Look what we have here, a linear function! We know that the domain and range of linear functions is the real numbers.
We can conclude that:
the domain of the function is
all the real numbers
the range of the function
is all the real numbers
Now, to find the inverse of our function, we are going to replace

with

; then, we are going to interchange

and

and solve for

:







The inverse of our linear function, is another linear function, so we can conclude that:
the domain of the inverse function is
all the real numbers
the range of the inverse function
is all the real numbers
B. 2
4x + 3 = 7x - 3
7x - 4x = 3 + 3
3x = 6
x = 2
Well we need an image to solve this
