12 is B. You because the graphs slope is 1. 13 is A 7 I think.
Answer:
the slope in the equation is 5, while the slope on the graph is 2
83/100 is 0.83 in fraction form
You'll want to use the quadratic formula:
-b (+/-) sqrt(b^2 - 4ac), all divided by 2a.
Under the square root you'll get:
-11
remember that the square root of -1 is i.
sqrt(-11) can be factored to sqrt(11*-1) and then sqrt(-1) * sqrt(11)
which becomes i*sqrt(11)
so your complex solution is:
-3 (+/-) (i*sqrt(11)), all over 4
