The graph gives information about how the charging time in hours of an electric car relates to its range given as a distance in kilometres.
(a) Find the gradient of the graph.
(b) Interpret what the gradient of the graph represents.
3. | GCSE Higher |
(a) Use the red graphs to solve the simultaneous equations:
$$4x-7y=-47$$ $$3y=-5x$$(b) Use the blue graph to find estimates for the solutions of the quadratic equation:
$$x^2-5x+3=0$$
If you would like space on the right of the question to write out the solution try this Thinning Feature. It will collapse the text into the left half of your screen but large diagrams will remain unchanged.
