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.
An example of a linear equation is y=x+3. The graph of this equation is a straight line running parallel to the x-axis at y=3. Linear equations may produce lines of any slope or location, but they always produce straight lines. An example of a non-linear equation is y=x^2+3.
