which equation represents the situation?

martin’s gift card
days
2 4 5 7
amount remaining 24.10 18.20 15.25 9.35

a.
y – 9.35 = −2.95(x – 7)

b.
y – 18.20 = 2.95(x + 4)

c.
y + 15.25 = −2.95(x + 5)

d.
y + 24.10 = 2.95(x – 2)

Complete the statements about the system of linear equation respresented by the tables the equation respented the left table is

Which situation can be modeled by the inequality 5 + 10w ≥ 45? a. you start with $5 and save $10 a week until you have at least $45. b.you start with 5 baseball cards and purchase 10 cards every week until you have at most 45 cards. c.you start with 5 water bottles and purchases cases of 10 water bottles each until you have a total of 45 water bottles. d.you spend $5 plus $10 per week until you have less than $45.

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.
