I will mark , help me with this question please.

Step-by-step explanation:

Since varies directly as we can write the relation as

where k is the constant of proportionality.

a) To solve for the k, we substitute the given values:

b) The equation relation x and y can be written as

c) When y = 9,

hello :

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

the lenght is : 35 y^8

the width is : 15y^6

tube or goog would be a great resource to with that question
