I believe it is the ratio 3 : 1.
<u>18 students chose the turkey sandwich</u>.
Since the class has a total of 24 students, we can deduce that <u>6 students chose the vegetarian sandwich</u>.
This gives us a ratio of 18 : 6.
When simplified, we get a ratio of 3 : 1.

Answer:
Step-by-step explanation:
The first step will be to make y the subject of the formula, by multiplying both sides of the equation by -1.
y = x - 1
This is simply the equation of a line with a slope of 1 and y-intercept (0,-1)
To determine the three points that solve the equation, we can let x be;
0, 1, 2
When x =0, y = 0-1 = -1
When x = 1, y = 1-1 = 0
When x = 2, y = 2 - 1 = 1
Therefore, we have the following three sets of points that can be used to graph the given linear equation;
(0, -1)
(1, 0)
(2, 1)
Find the attached for the graph
Answer:
In this problem, we are given the following functions:

and its inverse function:

First of all, we want to calculate
. This can be obtained by substituting
x = 2
into f(x). Doing so, we find:

Then we want to calculate
. We can do it by substituting
x = 1
into
. Doing so,

Then we want to calculate
, which can be found by calculating f(2) and then using it as input for
We know that
f(2) = 1
Therefore,

Then we want to calculate
, which can be calculated by plugging
x = -2
into
. Doing so,

Then we want to calculate
; by substituting
x = 4
into f(x), we find

Finally, we want to find 
We know already that

So we have:
