Concept explainers
Here we celebrate the power of algebra as a powerful way of finding unknown quantities by naming them, of expressing infinitely many relationships and connect ions clearly and succinctly, and of uncovering pattern and structure.
More puzzling. Three of your friends tell you they’ve seen a graph chalked in front of the math building. Leonhard says the graph is planar, with no loops or multiple edges. Kazmir says the graph has 50 vertices. Kenneth says the graph has 150 edges. If you know that Leonhard and Kazmir are correct, what’s your reaction to Kenneth? If you know Leonhard and Kenneth are correct, what’s your rcaction to Kazmir?

You are driving a car and are going to travel 60 km. Consider this to be a constant distance throughout the following discussion. If the trip took you: > half an hour, your average speed would be 120 km/h. > 1 hour driving, your average speed would be 60 km/h. > 2 hours driving, your average speed would be 30 km/h. Is this an example of direct or indirect/inverse proportion? Give a reas for your answer. C CHESK It is assumed that the value of a second-hand car is inversely proportional to the distance it has travelled. A car valued at R75 000,00 has an odometer reading of 80 000 km.
