1 Glycerin, an ingredient in some toothpastes, can interfere with strengthening your teeth. 2  Glycerin layers your tooth in a sticky film that keeps the minerals in your saliva from interacting with your enamel to strengthen it.. Chew sugar-free gum. The gum promotes saliva production, without the sugar that makes weakened enamel worse. Gum with the natural sweetener xylitol doesn't feed the bacteria that weakens your enamel, and xylitol has actually been shown to strengthen tooth enamel.
Demand functions for a straight-line demand curve take the following form: Quantity = a - (b x Price). where a and b are constants that must be determined for each particular demand curve. When price changes, the result is a change in quantity demanded as one moves along the demand curve.
The aggregate demand curve can be thought of just like a demand curve for a firm. When the price level is high, aggregate demand is low; when the price level is low, aggregate demand is high. The aggregate demand curve lies in a plane consisting of the price level and income or output. It shows a downward slope with price level on the vertical axis and income or output on the horizontal axis. As such, the aggregate demand curve outlines the relationship between income or output and the price level.
