The amount Lin's sister earns at her part-time job is proportional to the number
of hours she works. She earns $9.60 per hour. Write an equation in the form y=kx
to describe this situation, where x represents the hours she works and y
represents the dollars she earns. Is y a function of x? Explain how you know. Write
an equation describing x as a function of y,

Based on the information given, the equation will be y = 9.6x.

From the equation given, it was stated that the amount Lin's sister earns at her part-time job is proportional to the number of hours she works and that she earns $9.60 per hour.

Therefore, writing the equation in the form y=kx to describe this situation will be:

y = (9.6 × x)

y = 9.6x

Yes, y is a function of x.

Step-by-step explanation:

For a proportional relation, the equation is given by:

where k is the unit rate of change.

We were told that, Lin's sister earns $9.6 per hour.

This means k=9.6.

We substitute to get:

We could rewrite this as

Yes, y is a function of x.

To obtain an equation describing x as a function of y, we solve for x to get:

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
