Suppose that z varies jointly with the cube of x and the square of y. Find the constant of proportionality k if z = 14700 when y = 7 and x = 5.
k =

Using the k from above write the variation equation in terms of x and y.
z =

Using the k from above find z given that y = 10 and x = 9.
z =

o= 4(i) +3

step-by-step explanation:

o is your output value and i is your input value. so, for example, if we stuck 7 in as our input, we would first multiply by 4 ( pemdas ), which equals 28. then we would add 3 to 28, for a total output of 31. this may not be a graph, but, it is a way to solve your formula..
