Answer:
36 mph
Step-by-step explanation:
First, we have to find the unit rate of the money.
Since it's 15 dollars for each mile over the speed limit, divide 15 by 165.
The answer is 11, which means he was going 11 mph over the speed limit.
Add 11 to 25, and you get 36
The fourth set of ordered pairs is the function.
The definition of a function is that no matter what x value you put in, you get only one y value out. So no x value will have more than one answer. However, in the first 3 choices, you can see that each one has an x value that has two different y value answers.
In grouping 1, x = -1 gives us both y = 1 and y = -1.
In grouping 2, x = 0 gives us both y = 1/2 and y = 3/4.
And in grouping 3, x = -2 gives us both y = 1 and y = 2.
Therefore, the last grouping is your function.
Your answer would be 107. You can get this answer by following the rules of PEMDAS or Parentheses,Exponents,Multiplication, Division, Addition and Subtraction. Hope this helps! :D
