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,

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

step-by-step explanation:

one day the were 5 ducks, and their king told them to multiply their kingdom. so each went their own seperate way and met 4 other ducks on their journey.

when the ducks returned to their kingdom, it was discovered that there were 5 groups of 5 ducks. when the kind counted the number of ducks in total (including the ones he sent out earlier) he counted 25.

therefore 5 times 5 is 25.

the end. : )
