In inverse proportion x equals 2 and y equals 36 but what will y be when x equals 4?
Inverse proportion implies xy = c where c is the constant of [inverse] proportionality. x = 2 and y = 36 implies xy = 72 = c So the relationship is xy = 72 Then, if x = 4, y = 72/x = 72/4 = 18
Is xy equals 4 a function?
yes. it is a function
What is xy-2 when x equals 5 and y equals 4?
18
What is the constant of variation in y equals -4x?
It is -4.
What are the coordinated when x-2y equals 8 intersects with xy equals 24?
The coordinates are: (-4, -6) and (12, 2)

Complete the equation of variation where y varies inversely as x and y equals 4 when x equals 2?
xy = 8 or y = 8/x
Is xy equals 4 a function?
yes. it is a function

Suppose that y varies with x Write an equation for the inverse variation y 4 when x 7?
If y varies with x, then there cannot be an inverse variation between x and y!
What is the inverse of y equals 4?
Let N= inverse of Y Given 1/Y=4 ---> Y=1/4 inverse of 1/4 ---> 1/(1/4)=4 N=inverse of Y=4
What is the variation constant for an inverse squared relationship where we know x-4 and y3?

What is a direct variation?
A direct variation is when the value of K in multiple proportions is all divisible by the same number for example: XY=(1)(10) K=10 XY=(2)(20) K=40 XY=(3)(30) K=90 XY=(4)(40) K=160 In this situation the constant (K) of each proportion is divisible by 10 making the multiple equations a direct variation.
Is 4 plus 0 equals 4 an inverse property?
well it equals 4 any way you put
Is 2 plus 2 equals 4 the inverse operation of 4-2 equals 2?
yes
In the inverse variation function what happens to the output when the functions input value is multiplied by 4?
the output is divided by 4
What is the inverse of f of x equals 5x plus 4?
No, f(x) is not the inverse of f(x).
