Sparkles the Clown makes balloon animals for children at birthday parties. At Kelsey's party, she made 4 balloon poodles (x) and 5 balloon giraffes (y), which used a total of 18 balloons. For Herman's party, she used 14 balloons to make 4 balloon poodles and 3 balloon giraffes Choose the correct system of equations | 4x + 5y = 18 4x + 3y = 14 4x + 4y = 18 5x + 3y = 14 s x+y=18 8x + 8y = 14

Let hh represent the number of hummingbirds and ss represent the number of sunbirds that must pollinate the colony so it can survive until next year. 6h+4s > 746h+4s> 74 this year, 88 hummingbirds pollinated the colony. what is the least number of sunbirds that must pollinate the colony to ensure that it will survive until next year?

Ireally need subtract and simplify.(-y^2 – 4y - 8) – (-4y^2 – 6y + 3)show your work, ! i will mark you brainliest but you have to show your work.
