A"true or false" quiz consists of 10 questions. how many possible ways might the 10 questions be answered?

Well, if all answers are true OR false, and there are 10 questions only, then it would simply be 20 different ways, I believe.

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8

Do you need with the x value for the minimum? its always between the two intercepts for a parabola
