Alan learned a total of 10 appetizer recipes over the course of 2 weeks of culinary school. After how many weeks of culinary school will Alan know a total
of 15 appetizer recipes? Assume the relationship is directly proportional.

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6

step-by-step explanation:

divide, then simplify your answer.

1. make -15.66 ÷   5.8 a fraction. then divide.

2. simplify.  

3. final answer.  

since no one answered yet i will give it a shot, not completely sure tho.

i think it should be y=cos(x+2pi), (third answer, answer c)

good luck.
