I will give braniest and a thanks pln help Which equation is true when k = -15 A 3k - 11= -34 b -53 + 4k = 7 c k/3 + 17= 12 D k/5 + 2.5 = 0.5

8 is what i need help with and do u mind if u help with 9 to :> mate's

For problems 29 - 31 the graph of a quadratic function y=ax^2 + bx + c is shown. tell whether the discriminant of ax^2 + bx + c = 0 is positive, negative, or zero.

Suppose you just purchased a digital music player and have put 8 tracks on it. after listening to them you decide that you like 4 of the songs. with the random feature on your player, each of the 8 songs is played once in random order. find the probability that among the first two songs played (a) you like both of them. would this be unusual? (b) you like neither of them. (c) you like exactly one of them. (d) redo () if a song can be replayed before all 8 songs are played.

Solve each quadratic equation by factoring and using the zero product property. x^2 + 18x = 9x
