14. pizza palace offers five sizes personal: (8 inches) small: (10 inches) medium: (12 inches) large: (14 inches) and extra large: (16 inches) the cost c(d) of making a pepperoni pizza can be expressed as a function of the diameter d of the pizza. what is the average rate of change in cost from an eight inch to a sixteen inch pizza?

To calculate the average; add up all the numbers, then divide by how many numbers there are. In this case, there are 5 numbers; personal, small, medium, large, and extra large.
8 + 10 + 12 + 14 + 16 / 5 --> 60/5 = 12

22.

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

when multiplying or dividing by a negative on both sides you have to flip the inequality sign. this rule only applies to multiplying or dividing by a negative number in inequality equations. this rule is really important.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
