THE FREE ENERGIES OF FORMATION OF AQUEOUS d
... The employment of thermodynamics in biochemistry has been restricted, until recently, to the use of first law data. In the last few years a beginning has been made in the application of the second law; i.e., of free energy data (1, 2). The development of this field is limited by the paucity of avail ...

Direct Variation (5-3)
... To determine if a chart is a direct variation, find k for each pair. If k is the same for each pair, then the chart is a direct variation. If k is not the same, then it is not a direct variation. Tell whether the table represents direct variation. If so, write the direct variation equation Ex. ...

... We will use substitution for this one. Let’s solve the bottom equation for x. This way we won’t get fractions. Solving for x in the bottom equation will give us x = −2 y . Now we will substitute this into the top equation. Replace the x with -2y. Then you will have the equation: (−2 y ) y = −2 . Thi ...
