(quick note, I currently have 700 in Math, but March SAT was my first one, so I hope it will improve in the future) In the 3rd example (15x² - 32x + c = y), yes it is not efficient to plug the whole equation in desmos, but it is still useful to put 32² - 4(15)c = 0 because it reduces time and chance of error. Also, 256/15 is 6 characters long and 17.067 can be rounded to 17.07.

For 2, you can graph the two equations and see where they intersect. You can also estimate the solution as root of 3 is less than 2 and root of 5 is bigger than 2, so it becomes obvious in the grided diagram. 0 computation involved.
