Upon looking, you should see 4 points where the graphs intersect, so there are 4 solutions to the non-linear system of equations.
Two column proofs are organized into statement and reason columns. Each statement must be justified in the reason column. Before beginning a two column proof, start by working backwards from the "prove" or "show" statement. The reason column will typically include "given", vocabulary definitions, conjectures, and theorems.
1 to 2
Multiply by 2
2 to 3
Add by 1
3 to 6
Multiply by 2
6 to 7
Add by 1
7 to 14
Multiply by 2
14 to 15
Add by 1
Do you see the pattern?
Multiply by 2 and then add by 1; repeat the process.
Have an awesome day! :)
