Foundations & Pre-Calculus Mathematics 10 – 7.4 7.4 – USING A SUBSTITUTION STRATEGY TO SOLVE A LINEAR SYSTEM Focus: Use the substitution of one variable to solve a linear system. In the previous two classes‚ we solved linear system by graphing. A major shortcoming of this method is that at times we will only get an approximate solution‚ even if graphing technology is used. We can use algebra to determine exact solutions to linear systems. One algebraic strategy is solving by substitution

Biology 4U Exam Review Intro to Biochemistry Types of bonding: Ionic Results from the attraction between two oppositely charged atoms or molecules. They must lose or gain electrons to become charged. For example‚ a sodium molecule and a chlorine molecule form an ionic bond to create sodium chloride (NaCl) Covalent Results from the sharing of one or more pairs of valence electrons to create a stable molecule. For example‚ the covalent bonding of hydrogen ions creates hydrogen gas (H2)
