Answer:
Function; Not a function
Step-by-step explanation:
Write the ordered pair in the first set (x, y): (1, 11), (2, 7) , (3, 2)
Write the ordered pair in the second set (x, y): (1, 3), (1, 4), (2, 4) , (3, 2)
The first set in a function because no ordered pair has the same x value.
The second set in not a function because the x value is the same in two of the ordered pairs.
Answer
What are the numbers
Step-by-step explanation:
1/2 of the pizza is eaten in an hour. To get from 1/2 an hour to 1 hour, you multpily by 2. Multiply 1/4 by 2 to get 1/2.
You subtract 21 from 34, which leads you to -13 degrees F
Replace x with the value in the answers and solve for Y to see which ones match.
y = 1-4 = -3
y = -1-4 = -5
(1,-3), (-1,-5) is the answer.
