unable to be determined with given information. what's the whole angle or a formula?
In expressions such as "x-y", both "x" and "y" can have any value. The value of "x-y" will depend on what the value of "x" and the value of "y" are.
Yes; a line at 45 degrees.
45 degrees with respect to what?
If you mean: x+y = 30 and the value of y is 15 then the value of x is also 15
The value of x + y is indeterminate. You need the values of both x and y to determine x + y.
y is a function of x iffor each value of x (in the domain) there is a value of y, andfor each value of y (in the range) there is at most one value of x.
if 2x + y = 7, what is the value of y when x = 3?
Using x=oC and y=oF the conversion formula is 1.8x + 32 = y If x = y then 1.8x+32=x, solving for x yields -40 So, -40oC = -40oF
y = 4x as the value of y changes value of x changes by 4 times :) its simple
(x, y)-----> (-x, -y)
In most cases, x is independent and y is dependent. That is, you choose the value of x, but this x-value will decide the corresponding y-value.
If: y = x+b then y-x = b
