You can substitute the value of y(5/6 x + 1) from the first equation for y in the second and get
which becomes
and you get
I believe its 45.
Its hard to explain but what I can say is if you subtract the percentage with the total of the skins you would subtract what you had from there and then you would have 45.
Jason --> 126/6 = 21 pages per hour
joe --> 115/5 = 23 pages per hour
joe reads 2 more pages per hour
hope this helps :)
All of the equations have a graph that is reflected over the x axis. So look at the maximum point/ the vertex of the graph.
1) has vertex (3,4)
2)has vertex (-3,4)
3)has vertex (4,3)
4)has vertex(-4,3)
The functions should look the same, the only difference is the vertex.
