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
What is xy-2 when x equals 5 and y equals 4?
18
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
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!
Is 4 plus 0 equals 4 an inverse property?
well it equals 4 any way you put
What is the variation constant for an inverse squared relationship where we know x-4 and y3?
9
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 2 plus 2 equals 4 the inverse operation of 4-2 equals 2?
yes
What is the inverse of f of x equals 5x plus 4?
No, f(x) is not the inverse of f(x).
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
