The hibiscus, plumeria, and cassis petals are such a sweet-fruity flower smell that it reminds you of nectar instead of dry, dead flowers. Whereas most floral smells are dry, musky, and almost stifling this fragrance oil is sweet and almost a bit tangy.
The Standard Form for a linear equation in two variables, x and y, is usually given as Ax + By = C where, if at all possible, A, B, and C are integers, and A is non-negative, and, A, B, and C have no common factors other than 1.
Linear equations have the form a (x) + b = 0, where a is a linear function and b is a vector. To solve them, one uses algorithmic or geometric techniques, coming from linear algebra or mathematical analysis. Changing the domain of a function can change the problem considerably.
