Answer: 9
Step-by-step explanation: if the diameter of the pizza is 18 inches then the radius would be half of that, 9.
y=cos(x)+2
What is the amplitude of the function?
What is the period of the function?
First step: you got to add y to both sides in the math problem Ex: 15x - y + y < 12 + y
Second step: simplify 15x < 12 + y
Third Step: This you got to divide both sides by 15 like this: 15x/15 < 12/15 + y/15
Last and Fourth step: Simplify and thats your answer x < 12 + y/15
