I am so lost on this question. I’ve never heard of a matrices so I have no clue where to even start to solve this problem.

For an experiment, a penny is tossed. at the same time, a spinner with 8 congruent sections numbered 1–8 is spun. how many possible outcomes are there for the experiment?

Solve by any method (graphing, substitution or linear combination)y = x - 82x + 3y = 1a) (2, -6)b) (5, -3)c) (4, -4)d) (0, -8)i figured it out. the answer is (5, -3)

In which direction does the left side of the graph of this function point? a(x) = 3x - x2 + 4x - 2
