3Y*12X = 0 is equivalent to YX = 0
In functional form, it is Y = z*(X = 0) where z can have any value.
Here (X = 0) is
1 if X = 0 and the statement is TRUE
0 if X ≠ 0 and the statement is FALSE.
a = 8, b = 14.
Well, if you solve the equation for "y", you have "y" as a function of "x". Or you can do it the other way round; solve for "x", to get "x" as a function of "y" (the first option is more commonly used, though).
$48x + 5y" is an expression. It is not a function and so cannot be written as a function.
ln(a) = 5.3 a = e5.3
20/25 equals 0.8
a = 8, b = 14.
4x + y = 10 is a perfectly valid functional form. The standard form is 4x + y - 10 = 0
Yes.
x + y = -2 y = -x - 2 f(x)= - x -2
Well, if you solve the equation for "y", you have "y" as a function of "x". Or you can do it the other way round; solve for "x", to get "x" as a function of "y" (the first option is more commonly used, though).
3Y - 12X = 0add 12X to both sides3Y = 12Xdivide both sides integers by 3(3/3)Y = (12/3)XY = 4X---------------the function
X1 = -81
x = 3
Yes it is a function. In standard form it is y=x-4.
$48x + 5y" is an expression. It is not a function and so cannot be written as a function.
