Answer:
x - 3 ≥ 1
Step-by-step explanation:
Solving each of the inequalities
x + 3 ≥ 1 ( subtract 3 from both sides )
x ≥ - 2
3x ≥ 1 ( divide each inequality by 3 )
x ≥ 
x - 3 ≥ 1 ( add 3 to both sides )
x ≥ 4 ← required solution
I don't think there is a ratio for that I have only herd of stuff like "What is the ratio of 5 to 3.
You would write your 2 ordered pairs based on the year and the amount of yogurt sold in that year.
The x-value (your first number in the ordered pair) the year and the y-value (the 2nd number in the ordered pair) the amount of yogurt.
(2002, 2133) and (2007, 3478) would be your 2 ordered pairs.
We have the following function:

So if we graph this function we will get the Figure below. Thus, let's study both the equation and the graph to get some conclusions. Therefore, we can assure these statements:
First. The function is defined only for

as shown in the Figure. This is also true because of

where

must be greater (or equal) than zero.
Second. The range of the function are the values of

.
Third. If

creases then

always creases, too.
