I need help on this one it is questions that I need the answer like ASAP please if anyone with the right answer again please say something. 1. Rewrite y = -2x2 - 8x - 7 into vertex form
2.Rewrite y = -x2 - 8x - 11 into vertex form
3. Rewrite y = 3x2 - 6x - 1 into vertex form.
4. y = 2x2 +36x + 170 into vertex form.
5. Rewrite y = -x2 - 14x -59 into vertex form.

*If you can answer all I'll be very happy

Arianna is buying plants for her garden. she buys 15 flowering plants for $96. pink flowering plants sell for $8, and purple flowering plants sell for $5. how many pink flowering plants did arianna buy? i figured out the answer! the answer is 7. 8x +5y = 96 plug in 7 for x 8 (7) + 5y = 96 56 + 5y = 96 subtract 56 from both sides 5y/y = 40/5 y = 8 she bought 7 pink and 8 purple plants

Which shows one way to determine the factors of 4x3 + x2 – 8x – 2 by grouping?
