It equals XY.
The joint probability function for two variables is a probability function whose domain is a subset of two dimensional space. The joint probability function for discrete random variables X and Y is given aspr(x, y) = pr(X = x and Y = y). If X and Y are independent random variables then this will equal pr(X =x)*pr(Y = y).For continuous variables, the joint funtion is defined analogously:f(x, y) = pr(X < x and Y < y).

Variables X and Y are in direct proportion is Y = c*X for some constant c (not zero). Then X increases whenever Y increases and conversely. Y increases by c times the increase in X. Variables X and Y are in inverse proportion is X*Y = k for some constant k (not zero). Then X increases whenevr Y decreases and conversely.
x multiplied by y can simply be written as xy. You can't find the value of this expression, until you assume specific values for the variables, x and y.
X/3+Y There is no answer unless its equal to something X/3+Y=0 for example, or you have a value for the variables (1)/3+(2).
x5 You have x*x*x*x*x just add up the amount of x's you have and put it after as an exponent Example: 3*3*3*3=34 y*y*y*y*y*y=y6
You need to put all the variables on one side. Do this by adding or subtracting them.
The variables are x and y
-1
What is the question? Y changes as x changes. For example if y=4 x=43 3(4squared)-5 This is the equation for a straight line whicjhis found by making up different variables for y and finding x then graphing those coordinates
Oh, dude, x times y equals the product of x and y. It's like when you have x groups of y things, and you're too lazy to count them all out individually, so you just multiply them together and call it a day. Math, man, it's wild.
You could not graph (y-x-2) because it has no equal sign in it. In order to graph an equation, there must be a value that the numbers and variables are equal to. (e.g. y=2x+3)
