you have to solve y to get the answer
y=1/3x+3
There are no "following" data!
0.81 squared equals 0.81 x 0.81 The result in standard form is 0.6561
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).
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.
84.9 million equals 8,490,000,000%
