29 1.2. Constructing Direct Proofs 1. Let a, b, and c be real numbers with a 0. The solutions of the quadratic equation ax 2 + bx + c = 0 are given by the quadratic formula, which states that the solutions are xi and x2. where and x2 2a 2a (a) Prove that the sum of the two solutions of the quadratic equation ax2 + bx + c = 0 is equal to -b/a . (b) Prove that the product of the two solutions of the quadratic equation ax2 + bx + c = 0 is equal to c/a.
The proving of both a) and b) has been done

Answer: Y>5/6
Step-by-step explanation: I had this on khan Academy and got this right
I dont know the coordinates because i dont feel like putting them in right now buttttt........
main street bus equation is y=2x+40
County bus line equation is y=3x+20
thats all i've got.
The answer is -11 because if you subtract 7 from -18 you will get -11
