Answer:
linear
Step-by-step explanation:
The x-values all differ by 1, which is to say they are equally-spaced. The corresponding y-values all differ by -3. When (first) differences of equally-spaced values of y are constant, the function is of first degree, which is to say it is linear.
___
If second differences are non-zero and constant, the function is of second degree, quadratic.
Step-by-step explanation:
5.|12 - r| > 15
|12 - r| > 15/5
|12 - r| > 3
12 - r < -3 or 12 - r > 3
-r < -3 - 12 or -r > 3 - 12
-r < -15 or -r > -9
r > 15 or r < 9
1 pound = 16 ounces
16 ounces / 8 ounces = 2 servings per pound
5 pound bag x 2 servings per pound = 10 total servings
