Ake earns $12 for each hour worked. The equation y = 12x can be used to model this situation, where x represents the number of hours worked and y represents the total amount earned. What is the independent variable?

Independent variable: The number of hours worked(x)

Step-by-step explanation:

We are given the following in the question:

Ake earns $12 for each hour worked.

The above equation represents the total money earned where x represents the number of hours worked.

Independent and dependent variable:

Independent variable:

The number of hours worked, x is the independent variable in the given situation. A change in the number of hours worked leads to a change in the the total amount earned.

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024
